The hull form optimization under multiple operating conditions based on CFD technology
In order to reduce fuel consumption in actual operation,higher technical requirements have been put for-ward for the design of ship lines with multiple operating conditions and multiple speed points.In this paper,depend on the 3000TEU ship project,combined with the geometric characteristic of the straight bow,using the Feature function of the para-metric software CAESES,the linear transformation design module has been developed for the linear deformation of the bow front,and a four-variable linear optimization scheme was constructed.At the same time,Based on the Global calculation mode of SHIPFLOW software,the Sobol algorithm has been adopted,and the weighted algorithm was used to comprehens-ively evaluate multiple operation conditions.While the hydrodynamic performance remains unchanged under design condi-tions,the effective power under ballast conditions decreases by 2.65％,resulting in ship shape that is in line with engineering practice and relatively optimal.
