摘要
In the paper, the effect of moonpools in model scale on ship resistance in calm water was studied by numerical simulation for a multi-purpose vessel based on CFD tool. The RANS method, together with VOF method, was adopted for free wave simulation. The effect of moonpools was studied, considering bottom rounded radius and damping grid aperture ratio and the results of the numerical simulation were compared with those of model tests. Model test results reveal that the tendency on the effect of moonpools with bottom rounded radius and grid aperture ratio on the increment of ship resistance agreed with that of the model tests. The effect of bottom rounded radius is sensitive, but the higher the speed is, the weaker the effect on ship resistance is. The effect of damping grid aperture ratio is smaller than that of bottom rounded radius. © 2020, Editorial Board of Journal of Ship Mechanics. All right reserved.
