液体晃荡是液体储罐运输中的一种常见现象。液体波动导致罐壁上的波动力。不受控制的波动会导致巨大的力和动量。挡板可以控制这些波动。光滑粒子流体动力学（SPH）是一种被广泛用于模拟这种现象的数值方法。该方法的拉格朗日性质使其适合于模拟自由表面流动。在本研究中，一个精确的不可压缩光滑粒子流体动力学（ISPH）方法的发展和改进，使用核梯度校正张量，粒子移动算法，k-ε湍流模型，和自由表面粒子探测器。通过与实验数据的比较，验证了本文算法对浅水晃荡的模拟能力。本研究的主要目的是探讨垂直挡板对液体晃动阻尼的影响。结果表明，挡板数量对晃动波动阻尼有重要作用。
Liquid sloshing is a common phenomenon in the liquid tanks transportation. Liquid waves lead to fluctuating forces on the tank wall. Uncontrolled fluctuations lead to large forces and momentums. Baffles can control these fluctuations. A numerical method, which has been widely used to model this phenomenon, is Smoothed Particle Hydrodynamics (SPH). The Lagrangian nature of this method makes it suitable for simulating free surface flows. In the present study, an accurate Incompressible Smoothed Particle Hydrodynamics (ISPH) method is developed and improved using the kernel gradient correction tensors, particle shifting algorithms,k–εturbulence model, and free surface particle detectors. Comparisons with the experimental data approve the ability of the present algorithm for simulating shallow water sloshing. The main aim of this study is to investigate the effects of the vertical baffle on the damping of liquid sloshing. Results show that baffles number has a major role in sloshing fluctuation damping.
