Alternative Method of Calculation of Effective Wake with Radial and Tangential Shears

摘要

The partial differential equation for the perturbed pressure field of a propulsor operating in a non uniform flow was transformed into a simple form due to Goodman. Starting from the available solution for a flow with no shear, an iterative procedure was selected to derive a numerical solution for shear flow. The equivalent integral equation based on solving Laplace's equation would involve the numerical calculation of a five fold integral over an infinite computational domain for each interation.
