Evaluation of measured-boundary-condition methods for 3D subsonic wall interference

Measurements on a simple aircraft model in both an appropriately sized and a relatively large, low-speed, solid-wall test section were used to analyse the accuracy and consistency of measured-boundary-condition (MBC) methods. For completeness, the classical method of images, with two different correction procedures, was also analysed. For the...

Wind tunnel influence considering 2D high lift configurations

The present paper describes two alternative correction methods for wall interference based on measured boundary conditions. In both methods it is assipied that at or near the tunnel boundary the flow velocity will be measured in magnitude and direction and that the main part of the flow field may be considered irrotational and subsonic. One...
