Numerical study of thermochemical effects on the flowfield structure near the triple point at irregular reflection of shock waves

摘要

Effects of thermal non-equilibrium and dissociation on the flow structure near the triple point at irregular reflection of shock waves in a steady supersonic flow are considered by means of numerical simulations based on continuum and kinetic approaches. Numerical simulations are performed with Navier-Stokes and Direct Simulation Monte Carlo CFD solvers. Non-equilibrium numerical solutions are compared with three-shock solutions for equilibrium and frozen flows.
