摘 要 ：基于欧拉-拉格朗日法建立CCDM（combined continuum and discrete model）模型，全面考察液滴群碰撞聚并、液滴与载冷油介质之间的动量、能量交换以及颗粒冰之间的碰撞等，通过多工况模拟计算与试验数据验证，确定了采用不同颗粒碰撞求解模型的判别准则，获得了聚并颗粒的流动与换热特性。 关键词 ：颗粒冰；CCDM模型；颗粒；碰撞；数值模拟 Research On Ice Particles Collision And Production Model Based On Fluidized Theory Liang Kunfeng1 Peng Zhengbiao2 1.Henan University of Science and Technology, Henan Luoyang,471003 China； 2.Newcastle University, Newcastle,Australia Abstract: A CCDM （combined continuum and discrete model）was established based on Euler-Lagrange model. Some works are roundly investigated, including Collision- coalescence of drops, Momentum and energy Exchange between drop and coolant and Collision of ice particles. Discriminative rule is putted forward about the choice of model solving different state drops or ice particles Collision. The characteristic of coalescence particles flow and heat transfer is contained. Keywords : fluid ice; CCDM; particle;collision; numerical simulation
