NUMERICAL ASPECTS OF WU'S METHOD FOR CAVITATED FLOW, AS APPLIED TO SECTIONS HAVING ROUNDED NOSES

Abstract

This report describes the main features of a digital computer program for calculating the pressure distribution along bodies in two-dimensional cavity flow in an infinite, incompressible, inviscid fluid. The pressure distribution is used to compute drag, lift, and moment coefficients. The program is based on a theory of cavitated flows developed in recent years by Wu. In the present report, the theory is applied to flow configurations characterized by two fixed detachment points and from the restriction that there be no sharp corners interior to the wetted region. Calculations are presented for parabolic sections of 10-to-1 fineness ratio and 1-to-1 fineness ratio at several angles-of-attack.
