Discussion
Consider the following statements about shock reflection from a plane wall:
1. The reflected wave restores the flow to a direction parallel to the wall.
2. The reflected shock is not at the same angle as the incident shock.
3. The reflected wave is an expansion fan rather than a shock.
Which of the statements given above is or are correct?
Answer: C
The first two are correct: flow tangency forces the reflection, and the angles differ because the reflected shock acts on a slower stream. The third is wrong; a compression must be cancelled by another compression, so the reflected wave is a shock, not a fan.
