Teaching and study objectives
In the courses and research work, the fundamentals and applications of heat and fluid mechanics to energy technology appendices and components are to be taught and developed. The aim is to train future engineers, particularly in the field of renewable energies, and to carry out applied research.
Practical skills in dealing with application-orientated test systems are to be taught in the thermodynamics laboratory and in the technical centre.
Mobility as part of the energy sector and sustainable mobility will be covered as a further focus of research and teaching.

Bachelor's and Master's theses
The supervision of relevant Bachelor's and Master's theses (e.g. in the fields of combined heat and power, thermo-hydraulic issues, numerical and experimental) is gladly accepted.
The following theses are currently available in co-operation with SCHAEFFLER:
Thesis on the development of a concept for the utilisation of wind power
Theses and project studies in the Master's programme can currently also be awarded in the following subject areas:
A. Conceptual design of heat storage systems based on metal and ceramic foams
In many cases, thermal energy storage systems enable cost-effective and efficient additions to energy technology appendices as part of the energy transition. In addition to the storage capacity of a storage material, the material structure and manufacturability also play a role in the design of the storage capacity and performance of a storage system. As a result, the use of so-called metal and ceramic foams is seen to have advantages, at least for high-temperature storage tanks. With the help of calculations and measurements in the heat transfer wind tunnel, the suitability is to be tested.
Sub-tasks:
- Research storage tanks
- Research materials
- Proposal for storage structure
- Measurement of effective storage capacity, performance in the heat transfer wind tunnel
- Further calculations
B. Measurement of characteristic curve fields of a demonstration compression refrigeration appendix
The efficiency of compression refrigeration appendices, but also of identical heat pumps, is essentially determined by control parameters and operating parameters. A highly variable demonstration refrigeration appendix was created to investigate these influences. The task is to determine efficiency characteristic curves (COP_values) using a wide range of parameter variations and to work out certain effects:
- Variation of different parameters (V ̇_(air cold) ,V ̇_(air off),P_el,...)
- Determination of COPs in steady state
- Tracing of steady-state operating conditions in Excel using the determined values
- If necessary, make changes to the measurement technology
Prerequisite: Refrigeration-ventilation-air conditioning technology
C. Dynamic simulation of the demonstration compression refrigeration system with Modelica (OpenModelica, SimualtionX, Dymola)
The efficiency of compression refrigeration appendices, but also of heat pumps of the same design, is largely determined by control parameters and operating parameters. The structure of the appendix is to be modelled in a system simulation based on Modelica and transient operation is to be calculated. Work steps:
- Research similar work
- Simulation of the appendix with thermal masses and characteristic curves
- Comparison of simulation results with measurement results
Prerequisite: Refrigeration-ventilation-air conditioning technology
Further topics conceivable in the specialist areas:
- Adsorption heat pump Adsorption chiller
- Heat dissipation / cooling to the night sky
- Power 2 Heat demonstration with information utilisation from the Internet
