TIME-DOMAIN NUMERICAL EVALUATION OF SHIP RESISTANCE AND MOTION IN REGULAR WAVES BY USING THE CFD URANS METHOD
Abstract
Taking into account the International Maritime Organisation’s (IMO) strategy to radically reduce the GHG emitted by the shipping industry towards zero emission operation, today's assessment of ship behaviour in waves, its seakeeping characteristics and resistance and their interrelation with fuel consumption and emissions are one of the most attended research subject. There are three methods to conduct this analysis, which are Experimental Fluid Dynamics (FED), numerical methods e.g. Computational Fluid Dynamics (CFD) and empirical analysis. This study shows the results of time-domain analysis of ship motions and resistance in head sea waves by using the CFD method, which is then verified using the experimental results. The tests were run for different wavelengths for a KCS model. Numerical results, which are based on solving Unsteady Reynolds Averaged Navier-Stokes equations (URANS) show that the CFD method applied by using STAR CCM+ can be reliable for evaluating the ship seakeeping characteristics and resistance in waves.
