During reentry and hypersonic light of space vehicles through atmosphere real gas eects come into play. The analysis of such hypersonic lows is critical for proper aerothermal design of these vehicles. The present work emphasises numerical simulation of hypersonic ow with chemical non-equilibrium. A Reynolds Averaged Navier-Stokes code has been developed for this purpose employing an improved Roe scheme which is very robust and does not require any entropy x. To the best knowledge of the authors, such a formulation for real gas low has not been reported earlier. A circular cylinder test case for which experimental data is available has been used to validate the code.
