Special Features of Supercavitating Flow around Polygonal Contours
ABSTRACT
The method based on the classical solution of the two-dimensional nonlinear problem on supercavitating flow around the polygonal contour is presented. The program for calculation of hydrodynamic forces applied on cav-itators of complex shape and supercavitating hydrofoils with spoilers is described in this paper. Reasons of discontinuity of hydrodynamic characteristics of hydrofoils, rudders and propeller screws of high-speed vehicles in supercavitating flows are determined. Criteria of selection of physically realizable flows from the mathematically possible ones are proposed. Examples of calculation of wedge-shaped hydrofoils with cavitating spoilers are presented. The conditions of the static stability of polygonal cavitators are obtained.
