INVESTIGATION ON THE PRESSURE DISTRIBUTION ON SHIPS IN RELATION TO YAW ANGLE AND PATH CURVATURE
To learn more about the flow around a ship (or model) answering the helm, a better understanding of the pressure distribution is necessary. This requires that more should be known about the influence of the ship's yaw angle and path curvature on the pressure distribution, and an investigation on this influence has been conducted at the Wilhelm Pieck University, Rostock. Using slender-body theory and taking yaw angle and path curvature into consideration, the potential-theory pressure-distribution was calculated. To check the suitability of the results for boundary-layer calculations, pressure measurements were made on double models of a cargo ship in the cavitation tank and on a model of the same ship in the rotating-arm basin. Some important characteristics of pressure distribution calculated for oblique flow, including the position and magnitude of the minimum pressure points around the turn of bilge as well as the pressure-variation trends due to yaw and path curvature, were verified. Some other calculated values were, however, unreliable. The Authors discuss these and other results of the investigation in some detail. Order from: BSRA as No. 46,881.
