摘 要船舶泄漏带来的污染已经是海洋上污染物的主要来源之一。船舶一旦发生液货泄 漏，将给人类带来巨大的损失，给环境带来严重的污染。因此，对液货泄漏（原油泄漏、 化学品泄漏等）预防和有效控制已然成为改善海洋环境、维持海洋生态系统平衡、改善 人类生存环境的重要突破口。95147
本文针对这一问题，提出将移动粒子半隐式法（Moving Particle Semi-Implicit Method）用于模拟船舶舷侧发生破损时的泄漏过程。该方法是用粒子间的相互作用来代 替流体的运动。粒子包含了流体的运动性质，可以在外力的作用和内部粒子的相互作用 下运动。理论上可以用于任意变形的流体流动，并且容易实施。
对于液货泄漏，影响泄漏的因素较为复杂。本文希望运用 MPS 方法，通过控制变量 的办法来模拟舷侧破损泄漏的过程。分别从破口位置、破口大小以及内外液面高度差三 个因素来研究对泄漏的影响。为了增加实验的可靠性以及一般规律性，对于每个影响因 素，做了额外两组对比数值模拟。

Abstract
The pollution caused by ship breakage is one of the main sources of pollutants in the sea。When the ship comes into liquid cargo leakage,it will bring huge loss to humanand and serious pollution to the environment。Therefore,the prevention and effective control of liquid cargo leakage（crude oil spill,chemical leakage,etc。）has become an important breakthrough in improving the marine environment,maintaining the balance of marine ecosystem and improving the human survival environment。
Aiming at this problem,the Moving Particle Semi-Implicit Method is proposed to simulate the leakage process when the ship side is damaged。The method is to use the interaction between particles to replace the fluid motion。The particles contain the motion properties of fluid,which can move under the action of external forces and the interaction of internal particles。Fluid flow can be used in theory for arbitrary deformation and easy to implement。
For liquid leakage,the factors that affect the leakage are complex。In this paper,we hope to simulate the process of starboard leakage through the control of variables based on MPS method。 The effect of the leakage was studied from position of the damaged hole, dimension of the damaged hole and the height difference of the inside and outside surface。 In order to increase the reliability and general regularity of the experiment, two groups of numerical simulation were done for each influencing factor。
