Self-pumping transpiration cooling (A06*)

• Subject Area: Technical Thermodynamics ; Fluid Mechanics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 327154368

This project investigates experimentally the exchange of energy, momentum and mass between free-flow and porous media under turbulent, non-isothermal and evaporative conditions. The target application is a self-pumping transpiration cooling system, where inhomogeneities in thermal loads and/or porous media topology (e.g., due to clogging) affect locally the capillary forces and globally the coupling conditions at the free-flow/porous media interface. By measuring fluid and surface temperatures, time-resolved velocity and concentration fields, our objective is to identify the driving processes and formulate improved interfacial coupling conditions.
