1. Explain the Method of Characteristics. Can we use the method of characteristics to determine the contour of a supersonic nozzle? How? Show the right running and left running waves on flat plate in supersonic flow. 2. Show and explain the operation of Continuous Closed-Circuit Supersonic Wind Tunnel. Why is a converging diverging passage required to go from subsonic to supersonic flow? 3. What is The Shock Tube? Explain in brief detail "Fanno Line Flow" and "Rayleigh Line Flow". Bring out two important differences between Rayleigh Flow and Fanno Flow? 4. Show the hydraulic analogy between shock waves and shallow water waves. Explain with sketches. Compare the Mach Number with Froud Number. 5. What are subsonic and supersonic leading edges? Explain with sketches. Explain Transonic area rule with sketches 6. Illustrate Prandtl Meyer expansion round a convex corner? Define Mach Reflection and regular reflection?
