NUMERICAL-SIMULATION OF NONEQUILIBRIUM CONDENSATION IN A HYPERSONIC WIND-TUNNEL

A computational method for calculating supersonic two-dimensional nozz le flows with nonequilibrium phase change is developed, The code uses a fully implicit, finite volume formulation with Steger-Warming flux v ector splitting and Jacobi point relaxation. Source terms for finite r ate condensation and evaporation are constructed from the classical th eories of nucleation and droplet growth, Calculations of the NASA Lang ley Research Center 8 ft High Temperature Tunnel nozzle are performed and compared with previously reported quasi-one dimensional calculatio ns and experimental data.
