浅水效应对船舶阻力及流场特性的影响分析
Analysis of ship resistance and flow field characteristics in shallow water
摘要
Abstract
To analyze the characteristics of ship resistance and flow field in shallow water,we adopted a hybrid grid combined with the Reynolds-averaged Navier-Stokes (RANS) method and used the KRISO container ship (KCS) model in shallow water to perform numerical prediction and analysis.We adopted three unstructured grid methods to determine the most appropriate stern mesh generation method.By changing water depth,we analyzed the effect of water depth on the hydrodynamic performance of the ship.The results show that the shallow-water effect is distinct when the water depth h is less than 10 times the draft.With a decrease in water depth,the ship resistance coefficient,the suction force in the z direction,and the propeller flow fraction show increasing trends.With the decrease of water depth,the pressure difference between the head and the tail increases gradually,and the tail inclination is more obvious.关键词
