Abstract
This study presents a Vortex in Cell (VIC) method for incompressible flow around solid bodies. It is in conjunction with an Immersed Boundary (IB) method using a penalization term to satisfy the non-slip condition on the body surface. The presented method is applied to the two-dimensional simulation of the flow around a circular cylinder. The Reynolds number ranges from 100 to 1000. The Karman vortices are successfully simulated. The Strouhal number and the drag coefficient of the cylinder are favorably compared with the corresponding experimental results, demonstrating the validity of the simulation method.
