On threedimensional boundary layer flow over surface irregularities
Abstract
The threedimensional pipeflow boundary layer equations of Smith (1976) are shown to apply to certain external flow problems, and a numerical method for their solution is developed. The method is used to study flow over surface irregularities, and some threedimensional separated flows are calculated. Upstream influence in the form of socalled 'free interactions' requires an iterative solution technique, in which the initial conditions for the parabolic boundary layer equations must be determined to satisfy a downstream condition.
