PROPELLER POSITION OPTIMIZATION PROGRAM AND METHOD OF OPTIMIZING PROPELLER POSITION FOR VESSEL

摘要

PROBLEM TO BE SOLVED: To optimize a propeller position according to a shape of the stern of a hull.SOLUTION: A propeller position optimization program for a vessel includes: a step S10 in which flow field data according to the shape of the hull of a vessel and information concerning a propeller are obtained; a step S12 in which data for searching an optimum position are obtained to determine candidate searching positions of the relative position of the propeller to the hull; a step S16 in which an integral value F1 of the flow speed of the flow field heading for the axial direction of the propeller in the rotation range of the propeller for each of the candidate searching positions is calculated, and a distribution of an integral value F2 of the flow speed of the flow field heading for the turning direction of the propeller in the rotation range of the propeller to the radial direction of the propeller is calculated; a step S22 in which a position is specified where the integral value F1 becomes a minimum and the peak value of the integral value F2 to the radial direction of the propeller becomes a maximum; and a step S24 in which the specified position is outputted as the optimum position of the propeller to the hull.
