Abstract

Numerical solutions of 2-D steady incompressible flowinside a triangular cavity are presented. For the purpose ofcomparing our results with several different triangular cavitystudies with different triangle geometries, a general trianglemapped onto a computational domain is considered. The Navier-Stokesequations in general curvilinear coordinates in streamfunction andvorticity formulation are numerically solved. Using a very fine gridmesh, the triangular cavity flow is solved for high Reynoldsnumbers. The results are compared with the numerical solutions foundin the literature and also with analytical solutions as well.Detailed results are presented.
