The role of detailed combustion modeling and boundary layer modeling is discussed in comparison with experimental data for the seven injector GO2/GCH4 test cases developed at Technical University of Munich. Results show that unsteady Reynolds averaged Navier-Stokes equations are able to provide the evaluation of heat flux of the region close to injection plate with a reasonable agreement with experimental data. Conversely, the simplifying assumption of steady state expansion of combustion products, without detailed modeling of combustion, is confirmed to be reliable for the prediction of wall heat flux starting at 15-30 cm from injector plate.
