A Research Code to Study Solutions of the Boundary Layer Equations in Body Conformal Coordinates

Abstract

This report describes the development of a computer code to solve the two-dimensional boundary layer equations in direct, inverse or mixed direct/ inverse mode for airfoil flows. The solution algorithm uses body conformal coordinates and a relaxation scheme with flow-dependent operators. The code incorporates two methods to sweep the flow field. Topics include a description of the code structure, its input requirements, boundary condition and flow field initialization and various software tools required by the main algorithm. Finally, verification results are presented. This work seeks the development of a boundary layer code compatible with the NASA Ames ARC2D Navier-Stokes code. The two codes will be used in a study of the Fortified Navier-Stokes concept.
