Abstract
As relatively large models are often used in wind tunnel testing, the effects of the confining walls must be determined for effective test data correction. Corrections and predictions for flow about a flat plate normal to a confined flow have been investigated recently and, because of the complexity of the problem, have often been of an empirical nature. A comparison is made of the effectiveness of these methods for describing the flow around flat plates and their applicability expressed as a function of flow blockage by the body. The effectiveness of these methods is determined in part through data obtained from tests of flat plates of several sizes. In addition, a more representative parameter for determining both drag and vortex shedding frequency for any plate is developed, generalized from measurements of the flow field around flat plates in a wind tunnel.
