Euler and Navier-Stokes Computations for Two-Dimensional Geometries Using Unstructured Meshes

Abstract

A general purpose unstructured mesh solver for steady-state two- dimensional inviscid and viscous flows is described. The efficiency and accuracy of the method are enhanced by the simultaneous use of adaptive meshing and an unstructured multigrid technique. A method for generating highly stretched triangulations in regions of viscous flow is outlined, and a procedure for implementing an algebraic turbulence model on unstructured meshes in described. Results are shown for external and internal inviscid flows and for turbulent viscous flow over a multi-element airfoil configuration.
