説明

This paper is described on control of boundary layer on a flat plate by means of cavity flow. In this study, classifying the shapes of the cavities into 3,i.e. a rectangle, and arc makes discussion, and the depths of the cavities are systematically changed. At that time, it is to be explained based on the state of the cavity applied to a flow of plates in what a manner the internal part of the cavity will flow. Concurrently with this, it is also to be explained what a style of a flow the internal part will exhibit. Furthermore in accordance with numerical calculations and experiments, it is likewise to be explained what influence will be exercised on the boundary layer between the upstream and downstream flows. As a result, the following are made plain. By taking up properly the depth ratios (k/c) of the cavities complying with the individual cavity shapes, the boundary layer thickness in the upstream and downstream flows of the cavities can be controlled. Meanwhile with any of the cavities, existence of the minimum boundary layer thickness (δ/δ_m)_<min> is seen at a depth ratio.
