The Flow around an Inclined Flat Plate of Finite Width

Abstract

The flow around an inclined flat plate of finite width is studied mainly by the flow visualization techniques for intermediate angles of incidence. At the front surface, any separation of the leading edge does not occure, but the flow yaws towards the side edge and sheds as a side edge vortex. At the back surface, the flow can be characterized by three flows of the side edge vortex, a flow separated near the side edge of the leading edge and a flow separated at the middle of it. The core of the vortex stems from the vortex shed from the neighbourhood of the leading edge, and the vortex extends to the plate center with a decline of its intensity. The flow separated near the side edge of the leading edge is reattached in a short distance by force of the side edge vortex and ;moved towards the plate center. The other separated flow at the middle is disarranged into decay by the side edge vortex and becomes stagnant near the plate surface. These flow characteristics correspond well to the results of the heat transfer behavior.
