ASE 362K Problem Set #9 Clemens / Spring 2010 Due: Friday, May 7 Problem 1. Anderson Prob. 9.2. Problem 2. Anderson Prob. 9.3. Problem 3. Anderson Prob. 9.11 Problem 4. A Mach 3 flow of air flows past a wall as shown. The flow is isentropic and irrotational. A bump on the wall is thin enough that the flow can be treated with linearized theory. The bump has a shape given by the function 01 . 0 2 + = x y , which is valid between -0.1 < x < 0.1. Both x and y have units of meters . (a) What is the net force per unit span that acts on the bump in the x -direction? (b) What is the minimum temperature in the flowfield? (c) Estimate the Mach number at the location in the flow where (x=0.1, y=0.05).
