Unsteadiness of Cowl Shock/Convex Corner Interaction in an Inlet
Experiments in 2-D inlets for both sharp and round shoulders were conducted to study the influence of shoulder shapes and the relative position between the incident cowl shock and the shoulder on the unsteadin...

Shock Interaction on a V-Shaped Blunt Leading Edge
A V-shaped blunt leading edge configuration brings unavoidable hypersonic shock interactions which can result in an extremely high aerothermal load. Experiments and numerical simulations were carried out to st...

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...

Chapter and Conference Paper
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...
