| 摘 要： | 发展了一种新的用于模拟胶体运动的ＭｏｎｔｅＣａｒｌｏ方法，综合ｃｌｕｓｔｅｒｍｏｖｉｎｇ技术、粒子簇生长以及粒子沉降模拟方法于一个统一的模型中，首先对胶体体系中粒子的聚集行为进行模拟，在此基础上引入重力因素，考察中间体系的聚沉行为，并进一步扩展到水煤浆粗分散体系，分别从粒子簇、粒径以及粒子密度３个方面考察了超声辐照对水煤浆体系稳定性的影响规律，初步阐明了这些因素影响水煤浆稳定性的内在原因。

| Abstract: | A new Monte Carlo approach (MCA)is developed for the simulation of colloid particles subsidence simulation method are synthesized as one unite model.Based on the simulation of the particles aggregation in colloid system,gravity factor is introduced into MCA to investigate the aggregation and subsidence of intermediate system,and then those of coarse distribution system such as water coal slurry is studied at three aspects of particle size,cluster size and particle density,the essence of these parametres on the stability of water coal slurry is initially clarified. |
