Exact Supercavitating Cascade Theory

Abstract

A nonlinear exact theory to investigate a steady two-dimensional supercavitating flow past a cascade of arbitrarily shaped blades is presented. The solutions obtained by numerically solving a system of nonlinear, functional equations are compared with the available experimental data for flat-plate cascades and with linearized theories for both flat-plate and circular arc cascades. The force coefficients calculated with the present method show considerably smaller values than those of the linearized theories, as is expected.
