Abstract
The influence of the location of the lateral boundaries on 2D computat ion of unsteady incompressible flow past a circular cylinder is invest igated. The case of Reynolds number 100 is used as a benchmark, and se veral quantities characterizing the unsteady flow are obtained for a r ange of lateral boundary locations. The computations are performed wit h two distinct finite element formulations - space-time velocity-press ure formulation and velocity-pressure-stress formulation. We conclude that the distance between the cylinder and the lateral boundaries can have a significant effect on the Strouhal number and other flow quanti ties. The minimum distance at which this influence vanishes has been f ound to be larger than what is commonly assumed.
