Abstract:

The experimental investigation consists of two parts. Part I is a study of flow separation on a hydrofoil. A symmetrical, two-dimensional hydrofoil was towed with its plane of symmetry first parallel to the undisturbed free surface, and then at various angles of attack, at various velocities and depths. Part II is a study of flow separation on three stationary vertical struts passing through the free surface. In order to observe conveniently the flow pattern and the separation position, the experiment was performed in a glass-walled flume. Wall effect on separation was also studied in this flume by varying the ratio of the channel width to the model thickness.
