LAMINAR FLOWS PAST ELLIPTIC CYLINDERS AT VARIOUS ANGLES OF ATTACK

Numerical solutions for laminar incompressible fluid flows past thin elliptic cylinders at various angles of attack are obtained using a stream function-vorticity formulation. The flow is considered to be two-dimensional and time- dependent. Potential flow is selected as the initial condition. Almost steady-state solutions have been computed for the cases alpha = 0 deg, Re = 200;alpha = 45 deg, Re = 15;and alpha = 90 deg, Re=10 where alpha and Re are the angle of attack and the Reynolds number, respectively. Vortex shedding has been studied for alpha = 45 deg, Re = 30 and 200.
