WebQuestion:-Bow shock wave During a reentry, the space shuttle orbiter experiences high supersonic speed ( M 1), associated with strong detached bow shock wave, as shown in the figure.Behind the shock wave, however, it can still be assumed that the flow is subsonic (isentropic and calorically perfect ideal gas of air). A bow shock, also called a detached shock or bowed normal shock, is a curved propagating disturbance wave characterized by an abrupt, nearly discontinuous, change in pressure, temperature, and density. It occurs when a supersonic flow encounters a body, around which the necessary deviation angle of the flow is higher than the maximum achievable deviation angle for an attached oblique s…
