SPEED AND POWER PREDICTION TECHNIQUES FOR HIGH BLOCK SHIPS APPLIED IN NAGASAKI EXPERIMENTAL TANK

The model-ship correlation method applied in Mitsubishi Heavy Industry Ltd.'s Nagasaki Experimental Tank and its historical background are described. The method, which belongs to the category of theoretical methods, has been used for speed and power prediction of various kinds of ships during the past twenty years. The difficulty in power prediction caused by the rapid expansion in size and block coefficient has been overcome by the introduction of a three-dimensional extrapolation method in place of the two-dimensional one, without making any serious misleading prediction. For the current high block ships, it is essential to distinguish the type of flow pattern around the stern of the model since two kinds of flow pattern exist. The method used to distinguish the flow in the model and its influence on model-ship correlation are discussed.
