Laminar Boundary Layer Over Flat Plate in a Flow Having Circular Streamlines
Abstract
The laminar-boundary-layer development over a semi-infinite flat plate placed in a flow with concentric circular streamlines was investigated with the limitation of small total turning of the main-stream flow. The shape of the velocity profiles in the direction of the mainstream flow and perpendicular to it was analytically determined for an incompressible flow and a compressible flow with Prandtl number equal to 1. The boundary-layer thickness was shown to be proportional to the square root of the distance from the leading edge of the plate when measured along the streamline of the mainstream flow. The deflection of the boundary-layer flow at the plate surface from the direction of a circular streamline in the main flow was shown to vary directly with the turning. With increase in the Mach number of the mainstream flow, both the boundary-layer thickness and the deflection increased.
