Question

What happens to the velocity downstream of the shock as the deflection angle increases?

(a) Remains same

(b) Increases

(c) Decreases

(d) Tends to infinity

I got this question by my college professor while I was bunking the class.

This interesting question is from Physical Aspects of Conical Flow in section Linearized and Conical Flows of Aerodynamics

Answer 1

Correct option is (c) Decreases

Easy explanation: Using the shock polar, we notice that as the deflection angle is increased from θA to θB, the downstream velocity magnitude decreases due to the formations of stronger shock wave.
