Influence of Gaseous Contaminations on Performance and Operability of a Scramjet Inlet
The simulation of hypersonic flight condition on ground requires preheating of the working flow medium. The preheating process, however, may introduce a sort of side effect known as ‘vitiation’ or ‘contaminati...

On the Evolution of Reshocked Gas Cylinder Under Planar and Converging Shock Conditions
Richtmyer-Meshkov instability (RMI) [1, 2] arises when an interface separating two fluids with different densities is impacted by an impulsive acceleration. Due to the baroclinic mechanism, the initial perturb...

Generation of Air/SF6 Interface with Minimum Surface Feature by Soap Film Technique
The Richtmyer-Meshkov (RM) instability occurs on an initially perturbed interface subjecting to a sudden acceleration by a shock [2]. Due to the deposition of baroclinic vorticity, the initial perturbation wil...

Tests of Hypersonic Inlet Oscillatory Flows in a Shock Tunnel
For efficient operation, hypersonic air breathing engine requires the inlet to operate in a starting mode [1]. High backpressure induced by the combustion may cause the inlet to unstart in the engine actual op...
