Abstract

A "measured-boundary-condition" method for determining 2D wall interference has been developed. It applies measured "wall" pressure distributions and a model representation to determine the 2D interference flow field associated with the presence of the test section walls. Special attention has been paid to the model representation. The applicability of the method and some remaining questions are demonstrated by means of experimental results.
