Comparison of Computer Predicted and Experimentally Determined Leading Edge Cavitation of a Foil with Flaps.

Abstract

A model test and computer study were compared to assess the ability of a computer program to predict leading-edge cavitation inception. A 1/8 scale model of the PCH-1 forward foil was tested in the high speed towing tank at the David W. Taylor Naval Ship Research and Development Center and assessed by a two-dimensional computer program. Included is the method developed to take into account small flap angles. The results indicate that the two-dimensional program is able to make satisfactory predictions of leading edge cavitation for the PCH-1 foil when invested with three-dimensional values of the lift coefficient and the lift curve slope.
