Simulation of Transient Flow in a Shock Tunnel and a High Mach Number Nozzle

Abstract

A finite-volume Navier Stokes code was used to simulate the shock reflection and nozzle starting processes in an axisymmetric used tube and a high Mach number nozzle. The simulated nozzle starting processes were found to match the classical quasi-one dimensional theory and some features of the experimental measurements. The shock reflection simulation illustrated a new mechanism for the driver gas contamination of the stagnated test gas.
