AAE333 Fall 2011 Homework 8 Due: Mon Oct 31 (Note: This is a short one, because there are only 2 classes covered) R=radius of culinder U = free stream velocity (in x direction) = circulation about cylinder = /( ) ( ) RU nondimensional 1) For incompressible irrotational flow over a circular cylinder with circulation: 1.i. Calculate and plot the pressure coefficient Cp vs the angle from the forward stagnation point (upper and lower surface) for a range = [- -. . ] of circulation values 1 5 0 5 1 How does the shape of these curves change if you change the

Unformatted text preview: radius of the cylinder, or the free stream velocity or the free stream pressure? 1.ii. Draw the stream line patterns for each of the nondimensional circulation values = [- -. . ]. 1 5 0 5 1 Describe how the stagnation points shift as changes 1.iii. How far away from the cylinder do you have to go for the pressure coefficient to drop to .1 in magnitude? (at infinity, Cp=0, and on the surface it is something of order 1). You can address this be constructing isobars surrounding the cylinder....
