EAS 4101 - Aerodynamics – Spring 2011 1/1 4/1/11 9 th Homework 1. Consider an air wind tunnel at in which the stagnation conditions are at S.T.P. (as defined in Anderson). Assume that this magical wind tunnel permits the flow to be isentropically expanded to variable Mach numbers. Calculate and plot the static temperature, static pressure, static density, and expanded velocity for 12 0 M . What assumptions are needed to derive these equations and when do they breakdown? 2. Prove the following stagnation relations: 1 2 0 1 1 2 p M p  , 1 1 2 0 1 1 2 M    . In addition to stagnation flow, what other assumptions are required? 3. Prove the following normal shock relations: 2 1 2 2 2 1 2 1 2 1 1 M M M ,    2 1 2 2 1 2 11 21 2 M T M TM    , 2 2 1 1 2 1 P M P , and 2 1 2 2 1 M M  . What assumptions are needed to derive this equation?
