Full-potential (FP) method for three-dimensional wings and wing-body combinations - inviscid flow. Part 2: Use of FP and related programs.
Abstract:FP is a CFD (computational fluid dynamics) method coded in Fortran for calculating the flow field and aerodynamic forces of an isolated wing or a wing/body combination in a subsonic freestream, including the effects of shock waves. It utilises a relaxation process to solve finite-difference forms of the full nonlinear velocity-potential equation for the inviscid flow around the three-dimensional geometry. The FP method was developed over a period of years at ARA Bedford and RAE/DERA (now QinetiQ, Farnborough) and is made available under the terms of an agreement with QinetiQ. Used originally on mainframe computers, FP has provided valuable data in the design of a number of aircraft. With advances in computers, it has become possible to perform runs of FP on a PC within a few minutes.
An account of the principles of FP, and a number of examples, are given in Part 1. This Item, Part 2 in the series dealing with FP, deals with the practical aspects of running FP and its associated programs in order to obtain reliable results.
