AAE333 Fall 2010 Homework 10 Due: Mon Nov 15 10% bonus if turned in on Friday Nov 12 1) Consider the potential flow over a circular cylinder with circulation. The free stream is along the positive x axis. What circulation would be needed to put the rear stagnation point 20deg below the positive x axis? What would the corresponding values of Cl and Cd be? 2) You are going to find the incompressible potential flow over an NACA 2418 airfoil at angle of attack using the source/vortex panel method described in class. There are two matlab files you will need. function [U,V]=velfrompanel(x1,y1,x2,y2,xc,yc) calculates the x & y velocity components (U,V) at a specified point (xc,yc) induced by a unit strength source sheet connecting specified points (x1,y1) and (x2,y2). (or, equivalently, the velocities induced by a uniform strength vortex sheet) The second is an example for a different airfoil: airfoil_examp.m Before doing anything for the NACA2418 airfoil, make sure you can run the example, varying the angle of attack and the thickness/chord
