03.1 - Aerodynamics – CFD Methods and ValidationAPPLICATION OF DIFFERENT NUMERICAL TOOLS AND NUMERICAL METHODS FOR PREDICTION OF HEAT EXCHANGER RAMAIR-CONCEPTS FOR HYBRID ELECTRIC PROPULSION AIRCRAFT CONFIGURATIONSA.-R. Hübner¹, J. Kirz¹, K. Weinman¹; ¹German Aerospace Center (DLR), Germany To reduce the overall emissions of aviation hybrid-electric propulsion concepts have a great potential satisfying this challenge. For fuel cell applications heat exchangers are required to dissipate the waste heat produced by the fuel cell. The integration of the heat exchangers has an impact on the aircraft aerodynamics. With a new tool implementation for the simulations of heat exchangers in the DLR-TAU code, a generic application case is calculated and analyzed. |
