AAE333 Fall 2010 Homework 8 Due: Wed Nov 3 10% bonus if turned in on Monday Nov 1 1) For incompressible irrotational flow over a circular cylinder i. Calculate and plot the variation of pressure coefficient Cp vs the angle from the forward stagnation point (upper and lower surface) ii. How does the about pressure distribution change if you change the radius of the cylinder? iii. How does the about pressure distribution change if you change the free stream flow speed? iv. How does the about pressure distribution change if you change the free stream pressure? . v At what points along the body surface is the pressure equal to the free stream pressure? Draw . a sketch showing the points . vi How many cylinder radii up do you have to go away from the top of the cylinder before the gage
