Predicting Dynamic Separation Characteristics of General Configurations.

Abstract

A procedure has been developed for treating the dynamic interaction between a separated wake and a surface undergoing an unsteady motion. The basis of the method is an unsteady (time-stepping) panel method coupled with unsteady integral boundary layer codes. Pilot codes have been developed for both two and three dimensional conditions. Results presented here are mainly from the two-dimensional code in which the various routines for controlling the dynamic wake model have been developed. Some viscous/inviscid three-dimensional results are shown. The long term objective is to treat complete aircraft configurations through high angle-of-attack maneuvers. Keywords: Unsteady; Time stepping calculations; Dynamic separated wake model; Coupled viscous inviscid calculations.
