Abstract

© IAEME Publication.In this study, the numerical simulations of the steady incompressible viscous flow over a square cylinder are presented. Using an efficient finite difference numerical method together with a very large mesh, highly accurate steady solutions are obtained up to Reynolds number of 200. Our numerical results indicate that the strength of the vorticity at the center of the separation bubble increases until =100 and then starts to decrease with increasing Reynolds number. Good agreement is found with the results found in the literature. Detailed numerical solutions are presented.
