Abstract The effects of the wall emissivity on aerodynamic heating in a scramjet
are analyzed. The supersonic turbulent combustion flow including radiation is
solved in the framework of a decoupled strategy where the flow field is determined first and the radiation field next. In particular, a finite difference method
is used for solving the flow while a DOM (iscrete ordinates method) approach
combined with a WSGGM (weighted sum of gray gases) model is implemented
for radiative transfer. Supersonic nonreactive turbulent channel flows are examined for a DLR hydrogen fueled scramjet changing parametrically the wall emissivity. The results indicate that the wall… More >
