建立了传质引起的马兰戈尼效应的数学模型。水滴表面演化是通过水平集方法捕获的，其中界面由整个计算域中定义的标量距离函数的零水平嵌入集表示。在欧拉轴对称参考系中，对液-液萃取系统中不稳定运动中的可变形单滴之间的相间质量传递引起的马兰戈尼效应进行了数值模拟。对马兰戈尼效应的发生和发展进行了模拟，结果与经典理论分析和前期模拟吻合较好。
The mathematical model of mass transfer-induced Marangoni effect is formulated. The drop surface evolution is captured by the level set method, in which the interface is represented by the embedded set of zero level of a scalar distance function defined in the whole computational domain. Numerical simulation of the Marangoni effect induced by interphase mass transfer to/from deformable single drops in unsteady motion in liquid-liquid extraction systems is performed in a Eulerian axisymmetric reference frame. The occurrence and development of the Marangoni effect are simulated, and the results are in good agreement with the classical theoretical analysis and previous simulation.
