Two-dimensional wind-tunnel wall interference
An examination is conducted of two approximate methods for estimating the correction due to upstream flow inclination effects considered in Kemp's (1979) method; the methods are (1) an image vortex in the contraction, and (2) a rotation of streamlines passing through the test section upstream end. The magnitude of the corrections predicted by the two methods is different. The method based on the rotation of streamlines is noted to be in closer agreement with the results of the more refined calculations.
