Propeller-Induced Velocity Field by Means of Unsteady Lifting Surface Theory
Abstract
An analysis based on lifting surface theory has been developed for evaluation of the vibratory velocity field induced by an operating marine propeller in both uniform and nonuniform inflow fields. The analysis demonstrates how in the case of nonuniform flow the velocity at any field point is made up of a large number of combinations of the frequency constituents of the loading function with those of the space function. A numerical procedure has been developed adaptable to a high-speed digital computer and the existing program, which evaluates the steady and unsteady propeller loadings, the resulting hydrodynamic forces and moments and the pressure field, has been extended to include evaluation of the velocity field as well. The program could become a versatile and useful tool for the ship researcher or designer.
