Abstract

In order to increase the efficiency of currently available 10 MPa combustion chambers, hot gaspressures of up to 25 MPa are desirable. As such high pressures lead to an increased heat transferfrom the hot gas into the combustion chamber wall, alternative cooling methods to the conventional regenerative cooling are required. One of the most promising alternative cooling approach is effusion cooling. The advantages of effusion cooling are damage tolerance and a comparatively low weight. Since a few years DLR works on the field of effusion technology [1,2]. In the current paper, underlying CFD analyses are shown. These CFD analyses are based of the following principles: - rotatory symmetric model - solution of the Navier Stokes equations - coupled analysis of the hot gas and the coolant flow („multi species“) - compressible solution algorithm - ideal gas equation - k-e turbulence model in the combustion chamber - no turbulence model in the chamber wall - „distributed resistance“ according to Forchheimer in the chamber wall
