Karunya Advanced Aerodynamics Questions

Part – A : (5 X 16 = 80 Marks) (Answer any five from the following)
1. a. Describe how the principle of mass conservation leads to the continuity equation for incompressible and compressible flows. CO1 U

b. Interpret the relationship between stress and strain rate in a Newtonian fluid and explain the role of Stokes’ hypothesis in simplifying this relationship. CO1 U 

2. a. Define fully developed flow and state the conditions under which flow is considered fully developed in a pipe or channel. CO2 A

b. Define Poiseuille flow and discuss the important characteristics of laminar flow between two immiscible fluid layers in a horizontal channel. CO2 A 

3. a. Explain how the order of magnitude approach can be used to simplify the Navier-Stokes equations for a steady, incompressible flow over a flat plate within the boundary layer region. CO3 A 

b. Using the integral form of the momentum equation, calculate the friction drag on a flat plate and explain how boundary layer separation influences the result. CO3 A 

4. a. Define compressibility. Derive the expression for the velocity of sound in an ideal gas. CO4 An
b. Define pressure coefficient and discuss the corrections applied to a Pitot-static tube for subsonic and supersonic flow measurements. CO4 An

5. a. Compare normal shock, oblique shock and expansion wave with suitable examples. CO5 A
b. Derive the governing equations to determine the shock Mach number and pressure ratio in a shock tube for given initial driver and driven gas pressures. CO5 A 

6. a. Explain how the first law of thermodynamics is applied to compressible flow and describe the basic concept of pressure wave propagation in a gas medium. CO4 U
