ASE 362K Problem Set #3 Clemens / Spring 2010 Due: Friday, February 19 Problem 1. Anderson Prob. 3.2 Problem 2. A normal shock stands in air that is flowing at a Mach number of 1.8. The upstream conditions are P 1 = 1atm and T 1 = 300K. (a) What is the pressure, temperature and density downstream of the shock? (b) Compute the entropy change (units of J/kg/K) (c) Compute the rate of entropy production per unit area of the shock (units of W/K/m 2 ) (d) Repeat (b) for M 1 = 5 Problem 3. The space shuttle Columbia disintegrated at an altitude of about 200,000 ft (60 km) at which time it was traveling at about 12,500 mph (5500 m/s). As the shuttle enters the atmosphere it orients itself to provide as much lift as possible to slow it down (it is a “lifting body”). There is a strong shock that is formed over the entire windward side of the shuttle called the “bow shock” (like the “bow” of a boat). You are to compute the conditions behind the bow shock, which you can idealize as a normal shock.
