【摘要】：化工生产过程普遍涉及两相流动.两相流的数值模拟研究发展迅猛,对深入理解动量、热量和质量传递现象具有重要的指导意义.建立两相流和传递过程的数学模型并进行数值求解,特别是准确描述相界面的变形和运动,是当今两相流数值模拟研究的重点和难点.本文围绕含有可变形界面的两相流的数值模拟研究,主要介绍了两种典型的模拟可变形界面的水平集(Level Set,LS)方法和边界元法(Boundary Element Method,BEM).本文综述了近年来界面处理算法在含有可变形界面的两相流领域中的微流体、液滴撞击和溅落、气泡聚并破碎等数值模拟研究的现状和发展趋势.最后简要描述了两相流界面间质量传递的数值模拟方法.
[Abstract]:The chemical production process generally involves two-phase flow. The numerical simulation of two-phase flow has developed rapidly. The phenomenon of heat and mass transfer is of great significance. The mathematical model of two-phase flow and transfer process is established and solved numerically, especially for accurately describing the deformation and motion of the phase interface. This paper focuses on the numerical simulation of two-phase flow with deformable interfaces. This paper mainly introduces two typical horizontal set level set (LSs) methods and boundary Element method (BEM) for simulating deformable interfaces. In this paper, the microfluid, droplet impingement and splash in the field of two-phase flow with deformable interfaces are reviewed. The present situation and development trend of numerical simulation of bubble aggregation and fragmentation are presented. Finally, the numerical simulation method of mass transfer between two phase flow interfaces is briefly described.
