自由来流马赫数5.33,速度4860m/s的空气流经半径为101.6mm的球。 ü high enthalpy “hot” hypersonic flow (h0 = 16.01 MJ/kg, T= 2070 K) ü freestream Mach number of 5.33, freestream flow speed of 4.86 km/s ü detached bow shock where the shock stand off distance is sensitive to flow chemistry ü thermal non-equilibrium ü finite rate nonequilibrium chemistry ü comparison of a calorically perfect gas model to a reacting gas model 本次计算采用5步离解反应方程。 N2+M<->2N+M A: 3.6E+18, n: -1.6, E/R: 113200, ThirdBody Efficiencies: N2:1 O2:1 NO:1 N:3 O:3 O2+M<->2O+M A: 2.75E+16, n: -1, E/R: 59500 ThirdBody Efficiencies: N2:1 O2:1 NO:1 N:3 O:3 NO+M<->N+O+M A: 2.3E+14, n: -0.5, E/R: 75500 ThirdBody Efficiencies: N2:1 O2:1 NO:1 N:2 O:2/ N2+O<->NO+N A: 3.18E+10, n: 1, E/R: 37700 N2+O<->NO+N A: 216000, n: 1.29, E/R: 19220 不同组分分布
