NUMERICAL STUDY ON THE EFFECT OF LCB POSITION ON RESISTANCE OF BULK CARRIER 22000DWT BY CFD METHOD

Abstract

The paper presents the results of investigation on the influence of longitudinal centre of buoyancy (LCB) on resistance of bulk carrier 22000 DWT at different ship speeds using CFD method. The ship hull form with different LCB were produced from the initial one by using Lackenby method in MAXSURF modeler’s parametric transformation tool. Numerical obtained results indicates that changing trends and levels in ship resistance depend on LCB position and ship speeds. Finally, the paper conduct analyzing the differences in flow field around the ship hull form with variation of LCB position to fully explain the physical phenomenon in change flow around the ship with variations of LCB position.
