IMPROVED FIRST-ORDER SUPERCAVITATING THEORY,

Abstract

Conventional first-order supercavitating hydro foil theory is reviewed, and it is shown that, by avoiding the usual linearization of the physi cal plane, general expressions for improved force coefficients may be obtained in terms of the con ventional first-order coefficients. Specific examples are given including supercavitating flow about a cambered hydrofoil, a symmetric wedge and a flat-plate hydrofoil with flap. Comparison with exact solutions shows that the improved first order lift is generally within 5%, for angles up to 90. (Author)
