Addition of the Spanwise Effect of Gravity to Numerical Calculations for a Supercavitating Hydrofoil of Finite Span.

Abstract

The spanwise variation in pressure due to gravity (occurring in experimental work) was included in the numerical calculations of a supercavitating hydrofoil of finite span. The effect was negligible on the lift and moment coefficients but a small change in the cavity length was noticed at the foil centroid. The major change was in the cavity shape. The cavity predicted by the new numerical model was longer near the root and shorter near the tip as was expected. (Author)
