Unformatted text preview: AAE 334 Fall 2011, Homework 22 SOLUTIONS Due Friday, November 4 at the beginning of class. In lecture and Chapter 9 we are learning that the static thermodynamics through a steady oblique shock are the same formulae as for the steady normal shock if we use the upstream normal Mach number in place of the upstream Mach number. It turns out that this is also the case for the ratio of stagnation pressures (but not the 1 2 / p p o column in the tables!) Shock angle and wave angle are synonyms. Mach angle is different. Use formulas from the text to solve these problems: 1. Find the static pressure ratio for an oblique shock in a Mach 2.5 flow with shock angle of 40 degrees. Compare to the static pressure ratio for a normal shock in a Mach 2.5. 2. Find the static pressure ratio for an oblique shock in a Mach 2.5 flow with shock angle of 80 degrees. Compare to the static pressure ratio for a normal shock in a Mach 2.5....
