Upwash Interference on a Symmetrical Wing in a Rectangular Ventilated Wall Wind Tunnel: Part I. Development of Theory.

Abstract

The wind tunnel boundary upwash interference on a symmetrical finite wing of arbitrary lift distribution is calculated in a rectangular test section with solid vertical walls and ventilated (porous-slotted) horizontal walls. The interference is found by applying linearized theory for a compressible medium at subsonic speed to the boundary value problem. The theory uses an image method in addition to Fourier transforms with an equivalent homogeneous boundary condition on the ventilated wall. A treatment of the far downstream end condition consistent with the Fourier transform method is presented. (Author Modified Abstract)
