Chemical kinetics in a five-component air behind shock waves

Abstract The inuence of non-equilibrium kinetic processes on macroscopic parameters in air flows is a challenging and an important problem. Particularly, simulation with high-temperature effects near the surface spacecraft or meteorites when they enter Earth’s atmosphere. Non-equilibrium reacting five-component mixture consisting N2, O2, NO, N, O behind shock wave at different altitudes atmosphere speeds inlet flow are investigated. lengths relaxation zones considered to evaluate applicability one-temperature thermodynamics model for calculating fluid quantities wave. results obtained in-house code developed super-and hypersonic applications. from compared numerical calculations computed equilibrium
