中文摘要：
提出一种新颖的生成初始粒子信息方法，介绍了从图像直接生成初始粒子分布的过程，利用Matlab和C＋＋程序实现了复杂几何形状区域上初始粒子的生成，为粒子方法模拟复杂边界的多相流体系及流动、传递和反应相耦合的过程提供了有效支持。通过模拟肺呼吸的粒子初始化的实验表明，利用该方法能方便、准确地生成复杂的二维几何边界的初始粒子分布。
英文摘要：
A novel initial particle generation has been proposed which is directly generates initial particles messages from simulation layout with the help of Matlab and C ＋＋ program. It can generate initial distribution of particles for domains of complex geometry, which efficiently supports numerical simulation of muhiphase systems and coupled processes of flow, transport and reaction by particle methods. The study of initial particle generation for lung model shows, it is more ease and accurate to generate initial particles for two- dimensionless domains of complex geometry.
