Oblique shock diffuser has a better pressure recovery than a normal shock diffuser.

Oblique shock diffuser has a better pressure recovery than a normal shock diffuser. Correct Answer True

In an oblique shock diffuser, the accelerated flow is slowed down by a series of oblique shock waves followed by slowing down of the flow by a weak normal wave at the end of the diffuser. Therefore, the static pressure at the exit of the diffuser is equal to p∞. The pressure recovery in case of an oblique shock diffuser is greater because of lower total pressure loss compares to the normal shock diffuser.

Which of these phenomena attenuates the advantages of greater pressure recovery in an oblique shock diffuser?
Which of these factors contribute to additional total pressure losses inside the oblique shock diffuser?
Statement (I) : When a bluff body moves at supersonic speed in still air, an attached shock wave is produced at its nose causing the flow to be subsonic behind the shock plane. Statement (II) : A normal shock always transforms supersonic flow into subsonic flow causing increase in pressure, temperature and entropy.
In reality what happens due to the interaction of the oblique shock waves with the boundary layer on the walls of the diffuser?
