Abstract:

A previous report described a higher-order three-dimensional panel method that represents the body about which flow is to be computed by means of curved four-sided surface panels having linearly varying source and vorticity distributions. The method of accounting for lift was incomplete, and the main purpose of the present work was to remedy this defect. A number of other modifications to the method were also made to improve the efficiency and accuracy of the method. The modifications documented here are formulas for the edge-vortex influences, which previously had been neglected new surface vorticity formulas that express its influences in terms of source influences a modified global vorticity algorithm to improve continuity over the surface, and an extrapolated Kutta condition.
