This paper examines the influence of oblique perforated baffles on the sloshing dynamics of rectangular liquid storage tanks. The analysis presented accounts for sway induced hydrodynamic forces and entropy generation. Internal liquid free surface oscillation is modelled by the volume of fluid method. The effect of baffle geometric parameters, orientation and porosity on loads is examined and numerical results are compared against a set of experiments. Consequently, an engineering method suggesting the optimum size, angle of inclination and topology of baffles for the case of a rectangular tank is presented. It is shown that implementation of optimized oblique porous dual baffles may reduce sloshing loads by up to 15%.

本文研究了倾斜的多孔挡板对矩形液体储罐晃荡动力学的影响。提出的分析说明了摇摆引起的水动力和熵的产生。内部自由液体表面振荡是通过流体体积法建模的。检查了挡板的几何参数，方向和孔隙率对载荷的影响，并将数值结果与一组实验进行了比较。因此，提出了一种工程方法，该方法为矩形水箱提供了最佳的尺寸，倾斜角度和挡板的拓扑结构。结果表明，采用优化的倾斜多孔双折流板可以将晃荡负荷降低多达15％。
