Finite-difference analyses of the two-dimensional Navier-Stokes equations were given in stream function-vorticity formulations from the range of the steady state to the range of the unsteady vortex street behind a square cylinder placed in the middle of a flow channel between two parallel walls. For flows in a multiply-connected region, the value of the stream function on the body cannot always be given a priori. A new method to determine this value was proposed for getting the circulation flowing out of a control surface set behind the body. Transitional phenomenon from a steady state of the twin-vortices to an unsteady state of the vortex street was successfully reproduced with good agreement with experimental results.
