Kinetic Schemes over the years have become very useful and have been shown to be robust while computing inviscid flow for various types of bodies and for various flow regimes from subsonic to hypersonic flows. Further, algorithms based on meshless methods have shown to be more appropriate flow solvers for complex bodies. Re-entry vehicles enter the atmosphere at hypersonic speeds. The flow fields at theses hypersonic Mach numbers are chemically reacting, involving dissociation, recombination and possibly ionization of air molecules. The assumption of air as perfect gas at these Mach numbers is inaccurate and the real gas effects have to be taken into account to obtain realistic estimates of flow parameters. The objective of the present work is to incorporate real gas physics considering oxygen dissociation in the inviscid flow computations in the shock region to estimate flow parameters. The governing equations are modified assuming chemical equilibrium model.
