| 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. |
