Air flowing at Mach, M₁ = 9 with a pressure of 60 kPa and a temperature of -20°C passes over a wedge which turns the flow through an angle of 4° leading to the generation of oblique shock waves. One of the oblique shock waves impinges on a flat wall, parallel to the flow upstream of the wedge and is "reflected" from it. Find the pressure, Mach number, temperature, velocity behind the reflected shock wave. (2 points) ii. iii. iv. V. vi. vii. Find the total pressure, total temperature behind the reflected shock wave. (1 points) Also, calculate the overall entropy increase across incident and reflected shock. (1 point) Calculate the incident and reflected shock angles with respect to plate. (1 point) Sketch and mark regions across regions of incident and reflected shock wave in 0-B-M diagram (1 point) How much angle should the plate at "O" be turned to cancel the reflected shock wave. (1 point) Calculate the Mach number, temperature, pressure and velocity if at O the plate is rotated clock wise to 8 deg?
