Expansion fan

Question 1

Prove that a supersonic flow, after deflection at a convex corner, does not form a sort of ‘expansion shockwave’ at which flow parameters have a sudden change but its parameters are changing smoothly along the
flow (in contrast to flow deflection at a concave corner)

Question 2

Explain the shock expansion method for a flow over airfoils

Question 3

Describe the process of reflection of a shock wave from a slip line

Question 4

Describe the process of reflection of an expansion fan from a slip line

Question 5

What is the difference in wave pattern in the exhaust jet in the case of under-expanded and over-expanded
nozzle.
