Process engineering material and data


The working group for process engineering material and data deals with research questions on the subject of heat transport - from the basics such as determining the heat transport coefficient to the application in energy self-sufficient buildings or the energetic use of mine water.

Research domains


Energy self-sufficient buildings and quarters

From the point of view of the energy transition and the goal of climate-neutral building stock by 2050, the decentralized energy supply with renewable energies in buildings and neighborhoods is essential.

Main focus of work

  • Detailed energetic monitoring of building energy supply (solar energy application with high degrees of self-sufficiency)
  • Visualization of the measurement data from single and multi-family houses
  • Investigations of the operating characteristics of individual system components (solar thermal systems, heat storage, PV systems, battery storage, etc.)
  • Assessment of the comfort of the room air
  • Techno-ecological comparisons of different energy systems

Energetic use of mine water and near-surface geothermal energy

In order to achieve a decarbonisation of the energy supply in the future, the energy consumption for heating and cooling buildings is an essential lever. Both near-surface geothermal energy and the special form of energetic use of disused, flooded mines are very suitable for this. With mine water geothermal energy, special attention is paid to avoiding fouling through innovative heat exchanger design.

Main focus of work

  • Fouling in the heat exchanger: Increase in efficiency through innovative design
  • Determination of potential
  • Development of land use concepts
  • Plant monitoring
  • Heat pump concepts
  • Economic feasibility studies

Oxygen separation

Oxygen is one of the most important chemical intermediates in the world. In order to reduce the energy requirement for this production, the O2 separation with mixed conductive ceramic membranes is investigated. The main focus of the chair is the establishment of processes that only use (waste) heat and require little or no electrical energy.

Main focus of work

  • Investigation of the oxygen permeability and water vapor stability of various ceramic materials for oxygen generation
  • Development of a steam circulation process with an autarkic heat transport system with the highest possible degree of heat recovery and minimized use of electrical energy

Energy-efficient heat and material transport (e.g. heat pipes)

The transport of heat over a small cross-sectional area and the heat transport with as little effort as possible is a key issue when using renewable energies such as geothermal energy.

Main focus of work

  • Investigations into the film distribution in phase change probes with internally structured pipes
  • Pump-free heat transfer with thermosiphons and reverse thermosiphons
  • Investigations on the heat pipes with different fluids, e.g. nanofluids
