摘要

为抑制船舶液舱晃荡引发的船舶耐波性下降，降低相关航行安全风险，本文基于有限体积法求解流体控制方程，采用VOF法捕捉自由液面，构建垂直对称挡板的抑晃机理与流场特性数值模型。研究在横荡激励下，不同长度的垂直对称挡板制荡效果及其对液舱自由液面、舱壁压力、流场速度等流场特性的影响。结果表明：对于高宽比接近1的矩形液舱，在自由液面处垂直设置对称挡板可显著抑制晃荡；不同挡板长度的制荡效果差异明显，最优挡板长度设定为液舱宽度的0.7倍。

Abstract

To mitigate the deterioration of ship seakeeping performance induced by liquid tank sloshing and reduce the associated navigation safety risks, this paper employed the finite volume method to solve fluid control equations and utilized the VOF method to capture the free liquid surface. A numerical model was developed to investigate the sloshing suppression mechanism and flow field characteristics of vertical symmetric baffles. The study focused on the suppression effect of vertical symmetric baffles with different lengths under sway excitation, as well as their impacts on flow field characteristics such as the free surface of the liquid tank, tank wall pressure, and flow field velocity. The results show that for rectangular liquid tanks with an aspect ratio close to 1, the vertical installation of symmetric baffles at the free liquid surface can significantly suppress sloshing; the sloshing suppression effect varies significantly with different baffle lengths, and the optimal baffle length is set at 0.7 times the width of the liquid tank.
