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
