Question

Consider a Mach 4.5 airflow at a pressure of 1.25 atm. We want to slow this flow to a subsonic speed through a system of shock waves with as small a loss in total pressure a possible. Compare the loss in total pressure for the following shock systems: a. A single normal shock wave. b. An oblique shock with a deflection angle of 23.5°, followed by a normal shock. c. An oblique shock with a deflection angle of 23.5°, followed by a second oblique shock of deflection angle 15°, followed by a normal shoc
