Finite Difference Methods for the Solution of Unsteady Potential Flows.

Abstract

A brief review is presented of various problems which are confronted in the development of an unsteady finite difference potential code. This review is conducted mainly in the context of what is done for a typical small disturbance and full potential method. The issues discussed include choice of equations, linearization and conservation, differencing schemes, and algorithm development. A number of applications, including unsteady three-dimensional rotor calculations, are demonstrated. (Author)
