| 内容記述 | This study intends to perform successivily theoretical and experimental investigations about the flow around a semi-circular cylinder placed on a plane wan. The main purpose of the investigation is to relate the form drag of the semi-circular cylinder to the characteristics of the smooth-wall boudary layer on the plane wall which the semi-circular cylinder is placed. This report describes the pressure distributions and the form drag of the semi-circular cylinder with the aid of the theory proposed by the authors. This theory treats about two-dimensional incompressible potential flow and includes the assumptions derived from two empirical facts in order to construct the theoretical model. The first assumption is that the upstream flow of the semi-circular cylinder will be separated by force from the plane wall and will be reattached to the surface of the semi-circular cylinder. Consequently the maximum pressure on the surface will become the stagnation pressure. The second assumption is that the time averaged base pressure over the body surface exposed to the wake will be nearly constant. The pressure distributions on the surface of the semi-circular cylinder obtained by the application of the present theory are in close agreement with the experimental data. | |||||
