Boundary-layer stability analyses are performed of non-equilibrium reacting flows with surface chemistry (TPS fiber ablation). Such scenarios arise during atmospheric entry and hypersonic cruise missions. Flow stability studies allow to make physically-based predictions of the location of the onset of transition, which has a dramatic impact on both the surface heat flux and aerodynamic drag force.
