Abstract:

A general marching procedure for numerical solution of the two-dimensional boundary layer equations is presented. Although the present method traces its origin to that of Patankar and Spalding, major modifications have been undertaken. The method is tested for a variety of laminar flow configurations including wedge flows, incompressible flow on a flat plate at various Eckert numbers, compressible flow on an adiabatic flat plate at various Mach numbers, flow over a cylinder, uniform suction on a flat plate, and Howarth flow. The results show excellent agreement with solutions by other methods, even when as few as fifteen grid lines are used. A separate report entitled Film Cooling by Oblique Slot Injection presents results for a variety of injection configurations which show the effects of coolant mass flow rate, injection angle, boundary layer thickness, slot width, and multiple slots.
