Investigation of different modeling approaches for CFD simulation of high pressure rocket combustors

Kurzfassung

This paper summarizes the main topics and first highlights of the cooperation between DLR and ASTRIUM within the work package “CFD Modelling of Combustion Chamber Processes” conducted in the frame of the Propulsion 2020 Project. Within the addressed work package, DLR Göttingen and ASTRIUM Ottobrunn have defined several test cases where adequate test data are available and which can be used for proper validation of the CFD tools. In this paper the first test case, the Penn State chamber (RCM-1), is discussed. The achieved simulation results reproduce important validation parameters like the measured wall heat flux very well but also reveal some inconsistencies in the test data.
