Abstract:

A series of experiments was conducted on a model of a typical transom stern destroyer hull in order to obtain a detailed set of measurements of flow characteristics around such a hull. Measurements included total drag, wave drag, sinkage and trim, pressure, and wave elevation both alongside the hull and behind the transom. Predictions of these characteristics were made using two free surface potential flow computer programs, and were compared to the measurements. The correlation between predictions and experimental measurements was generally satisfactory, indicating that such computer programs may be useful tools in future investigations of the properties of transom stern flow.
