Shock Train Structures in Rectangular Ducts
The deceleration of a supersonic flow to subsonic velocity inside a high-speed engine occurs through a series of shock waves, known as a shock train. The generation of such a flow structure is due to the interaction between the shock waves and the boundary layer inside a long duct. This phenomenon is frequently encountered in a variety of internal flow fields where a shock wave interacts with the boundary layer including air-breathing engines, high-speed wind tunnel diffusers, and supersonic compressors and ejectors. The present study investigates the complex SBLI phenomenon encountered in a Mach 2 shock train through numerical analysis.
