Development of a selfadapted errorcontrolled difference method to solve the threedimensional laminar incompressible boundary layer equations by numerically given contours determined by points
Abstract
The solution of the 3D incompressible laminar boundary layer equations in streamline potential line coordinates is presented. The information about the 3D body configuration and the inviscid velocity potential is assumed to be given by points. The inviscid streamlines containing the information about the body by points are computed. A difference method solves the boundary layer equations with self adapted step size and order in the streamline direction and with given grid in the potential line direction with self adapted order. In the normal direction the grid and the order are optimized in the stagnation point and then remain fixed. The dividing streamlines, in which many streamlines coincide, cause a singularity of the boundary layer equations. The resulting computer program is given.
