In low-speed wind tunnel tests for a large-scale high-lift device model, the effect of wall interference is significant and the use of a classical wall interference correction technique becomes dubious. In this report, an attempt has been made to improve the reliability of wind tunnel data by using panel method together with the lift coefficient of the model and static pressure data on the tunnel wall. The method is then applied to a low-speed wind tunnel test using small and large rectangular wing models and the validity is examined. It has been found that velocity component perpendicular to the flow should be included to improve the accuracy of data in calculating the perturbation velocity on the wall.
