Reynolds Number Effects in Transonic Flow

Abstract

Reynolds number effects in transonic flow are critically reviewed. This review, which may be considered a supplement to AR 224 'Boundary Layer Simulation and Control in Wind Tunnel' (ADA-198667), is mainly concerned with a discussion of viscous effects actually observed on realistic configurations. The following geometries are considered: Airfoils and high aspect ratio wings typical of transport aircraft, fighter-type low aspect ratio delta wings, two- and three-dimensional bodies characteristic of missiles and combat aircraft fuselages, and afterbodies. 'Pseudo'-Reynolds number effects are identified which may arise, for instance, Due to the influence of the Reynolds number on the wind tunnel environment and in turn affect the flow about a model. As an introduction, a brief retrospect of the 'history' of Reynolds number effects is presented.
