Guidelines for Gridding Simple Flows - The Flat Plate in Laminar Flow

Abstract

In order to facilitate the application of Computational Fluid Dynamics (CFD) tools by aerodynamic designers, several guidelines are developed to quantify grid generation parameters for incompressible, laminar flat plate flows. These guidelines address several factors including: (1) domain size, (2) grid point distribution functions, (3) the error to be expected from a given initial point spacing, and (4) the number of grid points (or cells) in each coordinate direction. The guidelines are discerned by comparison of computed results with the classical Blasius solution. Then they are tested and verified for a case outside the bounds of cases from which they were developed. The result is a set of rules of thumb that greatly simplify the grid generation process for non-specialists.
