State if the following statements are True or False. Write down True" or "False" no explanations required. a. It is possible to stabilize the normal shock in the converging section of the diffuser section of a two throat supersonic wind tunnel. b. Finite waves can result in isentropic expansion and/or compression of the flow processed by them. The magnitude of vorticity of the flow downstream of a bow shock is zero. C+ characteristic can represent the path of both compression and expansion There is a net entropy decrease when a fluid particle is processed by a moving ?. d. waves expansion wave train

Explanation / Answer

The Answers are as follows

(a)False. It is possible to stabilize the normal shock in converging sections of the diffuser section of a two throat supersonic wind tunnel.

(b)True. Finite waves can result in isentropic expansion and/or compression of the flow processed by them.

(c)False. The magnitude of the vorticity of the flow down stream of a bow shock is zero.

(d)True. C characteristic can represent the path of both the compression and expansion waves.

(e)False. There is a net entropy decrease when a fluid particle is processed by a moving wave train.
