Three different coupled CFD analyses of the hot gas and the coolant flow in effusion‐cooled combustion chambers are shown. The common feature of these CFD analyses are the following principles: • solution of the Navier Stokes equations • multi species analysis including hot gas (steam) and coolant (hydrogen) • compressible flow • ideal gas • distributed resistance according to Forchheimer in the combustion chamber wall The differences between these models are given in the following table:The detailed analysis of the combustion itself is avoided by defining the injector plate of the combustion chamber (left boundaries of the colour plots in figure 2) as an inlet of the by‐product of the combustion (steam).
