In inviscid supersonic theoretical flow, is the d'Alembert Paradox applicable?
Homework Answers
d'Alembert's paradox states that for an incompressible and inviscid potential flow the drag force is zero for a body moving with constant velocity.
ie, for d'Alembert's paradox to be valid the flow should be
1 inviscid
2 potential flow
3 incompressible
Since the question refers to supersonic incompresiible theoretical flow , it satisfies the first two conditions while being supersonic (Mach number >1) itself implies that the flow is comprssible fluid flow . (Note that the flow is incompressible if Mach no is less than 0.3)
So the d'Alembert's paradox is not valid

Consider an imaginary method to generate a supersonic flow in a
two-step process of heating and cooling. Heat is first added to air
at a low Mach number, increasing the Mach number until the flow is
thermally choked at M = 1. Heat is then removed from the air, which
further increases the Mach number (this is the imaginary part, that
you were able to jump over M = 1 to the supersonic branch). Air at

Flow at Mach 3 reaches a 20º deflection, which creates an oblique shock with supersonic flow on both sides. Downstream of the oblique h shocks if the flow before the shocks was at standard sea level conditions? (You will need to find the local Mach number after the obligi shock in order to calculate the conditions of the normal shock. Give your final answer in K to at least the nearest integer.)
