WebAn oblique shock wave is a shock wave that, unlike a normal shock, is inclined with respect to the incident upstream flow direction.It will occur when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. The upstream streamlines are uniformly deflected after the shock wave. The most common way to … Below are a number of examples of shock waves, broadly grouped with similar shock phenomena: • Usually consists of a shock wave propagating into a stationary medium • In this case, the gas ahead of the shock is stationary (in the laboratory frame) and the gas behind the shock can be supersonic in the laboratory frame. The shock pr…
