Abstract:
The effect of the boundaries of a wind tunnel on the flow in the neighbourhood of a symmetrical body (i.e. (a) in two dimensions, a cylinder having a plane of symmetry parallel to the axis of the tunnel : (b) in three dimensions a body of revolution coaxial with the tunnel), may be represented on the assumption of irrotational flow to a first approximation as an increase in magnitude of the velocity at any point near the body in a constant ratio.
