Abstract

The unsteady starting process in the hypersonic nozzle of a free-piston shock tunnel is simulated using an inviscid flow model with equilibrium air chemistry. High-temperature effects are introduced using the equivalent gamma method and the thermodynamic properties of equilibrium air are given by curve fits. Results show the propagation behavior of strong shock waves in the starting process and the unsteady starting characteristics of an axisymmetric nozzle.
