Steady Incompressible Flow around Objects in General Coordinates with a MultigridSolution Method

摘要

The extension of a code to study flow problems around objects in two and three dimensions, with the use of an artificial interior boundary to solve single block discretization periodic boundary condition flow problems, is addressed. The steady flow in two dimensions around a circle and an ellipse is presented for a (relatively) low Reynolds number. The discretization, the adaptation of the existing multigrid solution algorithm to singular systems which appear in the smoothing algorithm, and steady flow results, are presented.
