Numerical simulations of the flow in a GOX/HTPB hybrid rocket engine are carried out with a Reynolds averaged Navier-Stokes solver including detailed gas surface interaction mass and energy balances. Global mechanisms are considered for the gas-phase chemistry. Results show the role of the gas-phase chemistry modeling and surface boundary condition modeling on the solution. The eect of chemical species distribution in the wall region on a nozzle carbon-carbon wall is finally discussed.
