Partially Cavitating Flows about Foils.

Abstract

A practical approach for predicting partially cavitating flow characteristics of foil sections is presented. The method take into account indirectly the viscous flow effects and the interaction between the fully wetted and perturbed cavitating flows. The partially cavitating flow characteristics are found to be sensitive to variations in the angle of attack, camber, thickness, and the thickness distribution. Some comparisons between the calculated and measured cavity lengths are made, and the results are generally in good agreement. Further developments needed in the future are also discussed. Keywords: Partially cavitating flows; Foils; Cavity length; Cavity volume.
