Two-dimensional wind-tunnel interference

Abstract

Exact solutions are given for the inviscid flow past two cylindrical profiles in tile centre of a stream of limited depth. The first of these relates to a nearly circular cylinder and the second to a thin section giving a constant pressure drop over the greater part of its surface. The stream has either parallel walls, constant pressure wails, or the boundaries may be partly parallel and partly of the constant pressure type. For the thin profiles the changes of thickness ratio required to give the same pressure distribution as in an unlimited flow are found.
