Hypervelocity cone-flow with reaction chemistry by second order kinetic theory based Euler solver

Calculations are presented of the hypervelocity Euler flow of nitrogen past a cone at incidence, at an enthalpy sufficiently high to produce dissociation/recombination chemistry downstream o the bow shock wave. A spatially second order accurate scheme for the numerical solution of the Euler equations based on the kinetic theory of gases is used, combined with the Lighthill-Freeman model of the non-equilibrium ideal dissociating gas. The result depict the effect of the interaction between gas dynamics and finite rate gas chemistry on the shape and strength of the shock induced vortex system near the flowfield leeward plane of symmetry
