Abstract

This work investigates the flow in the near field of a patch of distributed roughness in the high-enthalpy boundary layer of a generic, three-dimensional Apollo capsule geometry at an angle of attack of \(24^\circ \). Parallel Direct Numerical Simulations are performed for the laminar boundary layer on the windward side of the capsule for four different gas models. The effects of molecular dissociation as well as chemical and thermal non-equilibrium are presented for both the unperturbed flow and the flow behind the roughness. The development of the steady disturbances downstream of the roughness patch is analysed and quantified.
