State if the following statements are True or False. Write down True\" or \"Fals

Question

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

a) FALSE . It is not possible to do so. It is possible to stabilize normal shock in diverging section though.

c) FALSE. The magnitude of vorticity is enhanced during flow downstream.

d) FALSE The C+ represents the locus of forward wave only.

e) FALSE The process isentropic , so entropy cannot decrease
