Numerical solutions are obtained by means of a stream function-vorticity formulation for laminar incompressible fluid flows past a flat plate at the angles of attack α = 0°, 45°, and 90° with Reynolds numbers Re = 30, 50, and 200. The cross-section of the plate is elliptic and the flow is assumed to be two-dimensional and time-dependent. Potential flow is selected as the initial condition. Asymptotic steady-state solutions have been obtained for the symmetric configurations α= 0° and 90°, whereas the 45°-inclined plate always caused vortex shedding, even for Re as low as 30. The development of a Kármán vortex street for Re = 200, α= 45° is presented in detail.
