Why are shock waves associated to boundary layer interaction?
Here the interaction occurs due to the change in wall geometry, leading to a shock wave as the flow is turned. For higher ramp angles the boundary layer will separate, as for the shock impingement case. Indeed the two cases are very similar and the separation is controlled by the overall pressure rise.
What is shock interaction?
The shock interaction with a laminar boundary layer leads to a wide pressure diffusion in the upstream direction on the suction side resulting in a shock induced laminar separation bubble. Transition takes place inside the separated flow region and the turbulent boundary layer reattaches.
Can a shockwave BE Supersonic?
The shock wave travels faster than the acoustic speed of the undisturbed gas in the tube; it is a supersonic phenomenon.
Is Shockwave a good move?
1 Answer. Shock Wave would be a great temporary move, although when you can, Thunderbolt is definitely worth replacing Shock Wave with.

What happens when a shock wave hits a boundary layer?
When a shock wave interacts with a boundary layer, its main effect is to cause a sudden re- tardation of the flow, with subsequent thickening and, in many cases, separation of the boundary layer.
How are shock waves created in a diffuser?
They typically do this by inducing shock waves prior to the engine inlet. In this report several diffuser geometries were modeled to create oblique shock waves to reduce air speed with less stagnation pressure losses and drag than normal shock waves would create. These geometries include single ramp, double ramp, curved ramp, and a
Why are oblique shockwaves used in supersonic engines?
Oblique shockwaves are preferred because they create less pressure loss and drag throughout the system and make the engine more efficient. The two major geometries utilized in supersonic nozzle design are conic geometries and ramp geometries. Conic inlets are the most common design for air breathing engines and are
