This work presents a detailed analysis of the shock wave/boundary layer interaction in hypersonic flows around a double-cone. Numerical simulations have been carried out by solving the axisymmetric Navier- Stokes equations for an oxygen mixture. Thermochemical non-equilibrium is taken into account by employing the multi-temperature model (mT) proposed by Park and the State-to-State model (StS).

Abstract

This work presents a detailed analysis of the shock wave/boundary layer interaction in hypersonic flows around a double-cone. Numerical simulations have been carried out by solving the axisymmetric Navier- Stokes equations for an oxygen mixture. Thermochemical non-equilibrium is taken into account by employing the multi-temperature model (mT) proposed by Park and the State-to-State model (StS). The occurrence of surface processes is also analyzed considering both non-catalytic and fully-catalytic wall models. It is shown that the evaluation of correct free stream conditions is fundamental for the prediction of the separation extent and the corresponding heat transfer in high enthalpy conditions.
