ON THE SOLUTION OF INITIAL-VALUED BOUNDARY LAYER FLOWS,
Abstract
This report is concerned with the exact solution of the boundary layer equations, particularly when the initial conditions are not of a simple form. A comparatively new procedure is applied to the forementioned problem, and the preliminary results of the investigation are reported here. The theory is restricted to flows which are described by two coordinates. By replacing the normal partial derivatives by finite differences the boundary layer equations are reduced to an initial value system of coupled first order ordinary differential equations. Since these equations are classified as 'stiff', their solution requires special consideration. As an illustration, the velocity field of a two-dimensional wake is calculated, and the results are shown to be in good agreement with the solution obtained by full finite difference schemes. An improved theory is suggested and possible future studies are discussed. (Author)
