A General Solution For Wind Tunnel Boundary-Induced Interference In Two-Dimensional Subsonic Flow, Werner Johann Anton Dahm

Masters Theses

A general solution is presented for determination of wind tunnel boundary-induced interference in two-dimensional subsonic flow. The solution requires no a priori knowledge of the model geometry or tunnel wall characteristics, and instead, relates the interference to velocity measurements at a selected control surface within the tunnel. The solutions for the tunnel, free-air and interference fields are obtained using linearized subsonic theory with the Fourier transform technique. An analytical example dealing with the case of the wavy wall in the presence of a generalized tunnel wall boundary condition demonstrates the validity of the solutions in closed form. Numerical examples dealing …
