CAD (Apparatus and Piping Design)

Apparatus design deals with the design, construction, and testing of apparatus, as well as their structural elements and accessories, based on design data (pressure, pressure loss, temperature, mass flow rates). The goal is to commission a fully functional plant. Students specialize in the technical fundamentals they have learned so far, particularly statics, strength of materials, and materials science. They learn to work with technical standards and regulations. They understand that a design is not merely the solution to a technical problem, but that cost considerations are also necessary to succeed in the market.

Profile and Objectives

The engineering-based description of technical, chemical, and biological phenomena, as well as the definition of metrological requirements—including, and especially, those aimed at reducing environmentally harmful effects—always involves the application of physical laws and their interrelationships.

This requires a considerable degree of abstraction and the application of scientific and technical logic, which must be practiced. This degree of abstraction is a prerequisite for conceptual models and their metrological verification. A key tool in this process is the stoichiometric description of chemical processes.

• the instrumentation, and

• the basic approach to problem-solving

to the extent that they can apply them to specific engineering problems.

Overview

The Hands-On Lab offers first-semester students in the Maschinenbau and Materials Science programs the opportunity to gain hands-on experience with key components and machine elements. In the individual experiments, students assemble piping assemblies and disassemble and examine bicycle hubs. The lab combines hands-on work with introductory theoretical explanations of key topics that will serve as the basis for specialization later in the program. The following professors and staff members are involved in the Hands-On lab: Prof. Dr. Bernd Waltersberger, Prof. Dr. Jörg Ettrich, Prof. Claus Fleig, Prof. Dr. Günther Waibel, Jens Glembin, Ulrich Kuttruff, and Florian Faißt.

Pipe Joints Experiment

In this experiment, various pipe sections are assembled using different connection techniques. This includes a pipe run made of steel pipes connected using flanges. In addition, practice runs are assembled using galvanized steel pipes with screw-in connections, as well as hydraulic lines with compression fittings. Finally, these pipe sections are tested for leaks using a test pump. During the lab, students learn about the properties and advantages and disadvantages of the various pipe and connection techniques.

• Introduction to Informatik

• Fundamentals of Programming

• Through exercises in the computer science lab
  using a programming language, students practice programming techniques

Students understand the basic concepts of data representation and algorithm formulation in Informatik, are familiar with several important algorithms and data structures, and can apply them. They understand the basic elements of a programming language, can apply them, and are proficient in analyzing and creating simple structured programs.

The Machinery Lab focuses on the study and measurement of power and working machines. In addition, this is where the hands-on lab takes place, allowing first-semester students to gain practical experience assembling various components.

The umbrella term for power and working machines is fluid-energy machines. Fluid-energy machines are machines that convert fluid energy into mechanical energy or mechanical energy into fluid energy. Fluid-energy machines are indispensable both for the supply of electrical energy and as components in a wide variety of technical systems. These include water and steam turbines, compressors, and feed pumps.

In the Power and Working Machines Lab, students learn about the functioning of various fluid energy machines as a supplement to the lecture course. They conduct experiments and evaluate the results to specialize in understanding the characteristic properties of the machines.

The lab’s facilities are also used for the department’s own research projects and for research conducted in collaboration with industrial partners. In this context, individual machines are measured in detail and further developed, and new approaches for linking digital models with real components are designed and implemented. To this end, tools from computational fluid dynamics and the simulation of components and systems are employed, along with development environments for programming measurement and control systems.

Overview

The test benches in the lab allow for the examination of various power and work machines. Some of the test benches were built in-house, while others were purchased partially or entirely from external companies. The test benches are used for laboratory courses in which students from various semesters operate the equipment themselves and perform measurements. In addition, the test benches are used for teaching and research projects, particularly in the context of student projects.

The test bench enables the measurement of a radial fan within a piping system. Fans are fluid-flow machines used to move gaseous media such as air, for example, in residential ventilation and air conditioning systems. The most common types are centrifugal and axial fans, whose names correspond to the direction of airflow. Selecting a fan and determining its performance range requires not only an understanding of how it works but also knowledge of the fan’s performance curve and the system constraints that must be considered. 

Test Stand Configuration

The CAD diagram shows the components and measurement equipment of the centrifugal fan test stand. Air is drawn in by the fan through an inlet duct, which contains a standard nozzle for determining the volumetric flow rate. During operation, a pressure increase occurs at the fan outlet, measurable as the static pressure difference between the inlet and outlet. The fan is driven by a speed-controlled motor. A throttle valve is located in the discharge duct to vary the system resistance. In addition, a diffuser is installed in the discharge line, and its pressure drop is measured. The volumetric flow rate is measured on the discharge side using a thermal anemometer.

Test Bench Configuration

The single-stage piston compressor is driven by a drive unit via a belt. The intake air flows to the compressor via an intake tank; a Venturi tube measures the volumetric flow rate. The compressed air is delivered to a pressure tank, whose final pressure can be adjusted via a manual valve at the tank outlet. Temperature sensors are mounted at the compressor’s intake and discharge ports, and pressure gauges indicate the pressure in both tanks. By varying the final pressure and the compressor’s rotational speed, the compressor’s complete performance map can be determined.

Extension: Indicator Diagram

By installing additional sensors, it is also possible to record an indicator diagram on the reciprocating compressor test stand. An indicator diagram shows the progression of pressure and volume in the working chamber of a compressor during a working cycle, thereby providing a clear visualization of the processes occurring within the compressor. To achieve this, a miniature pressure sensor was installed in the compressor’s working chamber, and a rotary angle encoder was mounted on the pulley to determine the working chamber volume. The ability to generate indicator diagrams represents an important advancement of the test bench and expands the possibilities for courses in the mechanical engineering lab.

The compressor test stand at Hochschule Offenburg is a specialized test stand designed for research and teaching. It is a custom-built system that can be used to demonstrate and investigate educational content and phenomena from various disciplines, such as mechanics, thermodynamics, and fluid mechanics. For teaching purposes, this enables integrated and interdisciplinary work using the example of a fluid-flow machine operating at high rotational speeds. Furthermore, the test stand’s design allows for the investigation of compressors of various sizes and drive powers, as well as machine components of high-speed machines such as bearings and spindles.

Test Bench Design

Key elements of the test bench concept include the flexible mechanical mounting of the test specimens, which can be adjusted with high precision; high-quality measurement data acquisition; and flexible test bench control, which also enables automated test cycles. The sensor system includes a rotary piston gas meter with a humidity sensor for measuring volumetric flow, multiple measurement points for temperature and pressure, and sensors for measuring torque and rotational speed.

The test stand is used to study constant-pressure and overpressure turbines; a Pelton turbine and a Francis turbine are available for this purpose. Different head differences can be achieved by adjusting the inlet pressure, and it is also possible to vary the rotational speed. This allows, for example, the creation of performance curves for different rotational speeds while varying the guide vane angle (Francis turbine) or the needle valve position (Pelton turbine).

At the heart of the system is the respective turbine, which is connected to a braking unit via a belt. Water is supplied from a water tank, from which a speed-controlled circulation pump delivers water to the turbine; flow rate, pressure, and temperature are measured in this section of the pipeline. After passing through the turbine, the water is returned to the tank. On the Pelton turbine, a needle valve can be used to adjust the nozzle cross-section at the inlet; on the Francis turbine, a lever can be used to adjust the position of the guide vanes accordingly.

The Kaplan turbine is a so-called “high-speed” turbine with a high specific speed. It is used for large flow rates and low heads, i.e., for run-of-river power plants. A Kaplan turbine with a spiral casing has been set up in the mechanical engineering laboratory, where its operational behavior can be studied.

Test Bench Configuration

A submersible pump draws water from a deep basin through a pressure pipe and into the turbine, from which it flows back into the basin via an open channel and an overflow weir. By adjusting the pump speed via a frequency converter, the pressure upstream of the turbine can be varied, thereby specifying a variable geodetic head. The water enters the turbine through a spiral casing and flows radially through a guide vane assembly, whose blades can be rotated collectively by an adjustment ring. This changes the flow cross-section and the volumetric flow rate. The axial impeller can be observed through the Plexiglas suction pipe, where the adjustment of the impeller blades—which can be adjusted via a tie rod—can also be monitored. To determine the volumetric flow rate, both a magnetic-inductive sensor and the overflow weir in the water channel are used. For this purpose, the water level is measured using a float tube connected to the channel.

Wind tunnels are used for aerodynamic testing of (partial) objects such as airplanes or automobiles. The wind tunnel in the Lab for Power and Working Machines is used as part of lab courses to measure the flow around an airfoil. In addition, the test stand is used in projects, such as for components of the “Schluckspecht”—Hochschule Offenburg’s energy-efficient vehicle.

Test Facility Design

The wind tunnel at Hochschule Offenburg is of the Göttingen type, meaning the air circulates in a closed loop. The measurement section is open, allowing the test object to be visible and accessible. The flow is maintained by a frequency-controlled fan. The flow velocity is measured using a Prandtl tube and a Betz manometer. As part of the laboratory experiment, the pressure distribution on an airfoil is measured using a multiple U-tube manometer, and the force is measured via a bending beam with attached strain gauges.

Pumps are machines used to move liquids. Applications include, for example, circulating liquids within closed-loop systems such as heating systems, metering liquids, and emptying or filling containers. Pumps come in various designs and sizes. The pump performance curve, which represents the relationship between head and flow rate, is used to characterize a pump’s operating behavior. On a pump test stand, it is possible to determine such a performance curve using measurement techniques.

Test Stand Configuration

At the center of the test stand is a three-stage centrifugal pump driven by a frequency-controlled motor. The pump is integrated into an assembly with connection ports for pressure measurement. Other hydraulic assemblies include a valve control system, a water reservoir, and various flow meters. Each assembly has two ports to which a hose can be connected via a quick-connect fitting. In this way, the assemblies can be connected in any configuration to form a complete system.

Modular Operation of the Test Bench

The test bench allows the test procedure to be adapted to the required specifications and the time available. The most comprehensive and time-consuming option involves independently defining a measurement system and its hydraulic circuitry, representing the system in a flowchart, electrically connecting the sensors to the data acquisition system, configuring the measurement system within LabVIEW, and conducting the experiment followed by data analysis. By pre-configuring individual steps, the time required and the complexity of the experiment can be reduced.

Rotating machinery contains rotating shafts as essential components, to which the impeller, among other parts, is attached. Since the mass distribution in the rotor is not completely rotationally symmetric, vibrations occur during operation. In the critical speed range, these vibrations are so severe that they can destroy the component. In practice, therefore, care must be taken to remain below the critical range or to pass through the critical range quickly. The test bench investigates these dynamic problems using a simple, vibrating system—the Laval rotor.

Test Bench Configuration

The test setup essentially consists of three components: the drive unit, the control unit, and the shaft. A speed-controlled induction motor drives a shaft via an elastic claw coupling; the shaft is mounted on two bearing blocks using self-aligning ball bearings. A mass disc is mounted on the shaft, onto which a corresponding imbalance can be applied using weights of varying masses. Depending on the rotational speed, the shaft’s deflection is measured using acceleration sensors and displacement transducers. A catch bearing limits the shaft’s movement in the near-resonance range to safe deflections.

Computational Fluid Dynamics (CFD) is an important complement to analytical and experimental fluid mechanics. Using numerical methods, it enables the simulation of fluid flows and heat transfer for a wide variety of objects. In the Lab for Power and Working Machines, models of fluid-flow machines are developed as part of various projects, and their accuracy is verified through measurements on the respective test benches. The models are used to analyze the machines and to develop and evaluate optimization strategies. Various commercial and open-source simulation environments are used.

Profile and Objectives

Illustration and practical application of the mechanical processes covered in the lectures “Particle Technology” and “Mechanical Process Engineering” or “Dimensioning Fermenters.”

Equipment

1. Pressure filtration setup for pressures up to 6 bar

2. Sieve tower with sieves ranging from 45 µm to 8 mm mesh size

3. Laboratory stirring setup (capacity 3 l)

4. Pilot-scale stirring setup (capacity 30 l)

7. Flow measurement stand

8. Rotational viscometer

In addition, accessories from the general lab and pilot plant inventory, such as a compressed air network, CO₂ cylinders, scales, vacuum pumps, pH probes, oxygen probes, and stopwatches

Practical Applications

Re 1: Surface filters are used in a variety of ways, for example, for the mechanical dewatering of slurries, for water treatment, and for dust removal from gases. Determining the hydraulic resistance of filter cakes and filter media provides fundamental data for the selection and design of filtration equipment.

Re 2: Particle size and particle size distribution are important physical properties of materials and material systems. They determine, for example, flowability, wettability, and thus solubility properties, leachability, or the respirability of particles. This is not only relevant to particle behavior in process engineering but is also encountered daily in household settings (e.g., with sugar, ground coffee, instant coffee, and powdered cleaning agents). Sieve analysis is presented as an important measurement method for larger particles.

Regarding 3. and 4.: Agitation and mixing of liquid systems represent one of the most important basic operations in process engineering. The determination of a suitable agitation system and the required rotational speeds and agitation rates, as well as mixing times, mass transfer coefficients (kLa values), and torques serves as the basis for the process engineering and mechanical design of agitators, e.g., for homogenization or for the dispersion of a gas. Using two agitator setups of different sizes (lab and pilot-scale agitator setups), the principles governing scale-up can be determined.

Regarding 5.: In what appears to be a playful manner, measurements of the fall times of balls of different densities and sizes from various heights can be used to assess the validity of laws of falling bodies—namely, frictionless fall (mass-point mechanics) and fall subject to friction (in the Stokes, transitional, and Newtonian regions), be assessed.

Re 6: Solid-material silos are found in a wide variety of industries, e.g., as storage containers for granules in the plastics processing industry or on farms for storing grain. The test rig allows for investigations of the outflow behavior of free-flowing bulk material from solid-material silos and the subsequent weighing of the bulk material to determine and control its mass flow.

Re 7: In process engineering equipment, a wide variety of methods are used to measure volumetric and mass flow rates as well as flow velocities of liquids. In the experiments, typical methods are compared, and calibration curves are generated for the measuring instruments. At an additional level, the roughness of pipes can be determined, which is a major factor contributing to pressure loss in turbulent flows.

Re 8: Along with density, dynamic viscosity is the most important physical property of liquids in the design of many process engineering apparatuses and systems, such as stirred tanks, chemical reactors, fermenters, distillation columns, pumps, and piping networks. For this reason, rheology (the science of fluid flow behavior) is an important supporting discipline for process engineering.
