Prediction of the wind tunnel Sidewall effect for the iGREEN wing-tailplane interference experiment

Abstract

Computations using the DLR TAU code are presented to predict the effect of the wind tunnel on models which are directly attached to the wind tunnel side-wall. Results show that the effect of the sidewalls is similar to an offset in the angle of attack (but can only partially be corrected by a change in α), and that this effect is proportional to the lift and Mach number. These results were used in the design phase for the iGREEN wing-tailplane interference experiment. © 2010 Springer-Verlag Berlin Heidelberg.
