Multi-Grid Calculation of Three-Dimensional Transonic Potential Flows,

Abstract

A multi-grid algorithm has been developed to speed the iterative convergence of calculations for the transonic potential flow past swept wings and wing-fuselage combinations. The method is based upon a fully-conservative, finite-volume approximation to the steady potential equation which is second-order accurate everywhere in the flow field except near shock waves. The multi-grid scheme is incorporated within the framework of an alternating successive-line-overrelaxation (SLOR) solver of the difference equations. Computated results confirm the second-order accuracy of the scheme, and demonstrate the effectiveness of the multi-grid procedure. (Author)
