A Numerical Study of the Test Time in a Hypersonic Shock Tunnel.
Abstract
A numerical study was made of the test time in a hypersonic shock tunnel for Mach 10 flow. Harten's total variation diminishing (TVD) scheme was used to simulate the entire shock tunnel operation from diaphragm rupture to disruption of the flow in the nozzle. The code was able to model the main features of unsteady flow in a shock tube to include the shock wave and contact surface intersections. Results were obtained that predict the steady flow duration time for stagnation temperatures of 1200F, 2700F, and 6900F. Both air and helium were used as driver gases with air as the test gas.
