In the current study, three-dimensional models were established to simulate the transient formation and dripping of droplets during Electroslag Remelting (ESR) of steel, combining the κ-ε two-equation turbulence model, Volume of Fraction (VOF) multiphase model, and Magnetohydrodynamics (MHD) model. The influence of the interfacial tension on the varied size distribution and the transient dripping velocity of droplets were calculated and statistically summarized. The absolute velocity distribution of droplets showed that all the fluid inside the droplet flowed downward, while the relative velocity distribution illustrated a recirculation inside the droplets, indicating that the flow of molten steel inside the droplet have two kinds of motion: a downwards flow due to the gravity and a recirculation inside the droplet which led to the deformation of droplets.With a melting rate of 0.03 kg s⁻¹, the equivalent diameter and the dripping frequency in functions of the interfacial tension were D = 0.0119 σ^0.23 and f = 1.45 σ ^−2.37, respectively.

在目前的研究中，建立了三维模型来模拟钢的电渣重熔 (ESR) 过程中液滴的瞬态形成和滴落，结合κ - ε两方程湍流模型、分数体积 (VOF) 多相模型和磁流体动力学 (MHD) 模型。计算并统计总结了界面张力对液滴不同尺寸分布和瞬态滴速的影响。液滴的绝对速度分布表明，液滴内部的流体全部向下流动，而相对速度分布表明液滴内部存在回流，表明液滴内部的钢水流动有两种运动：液滴内部的重力和再循环导致液滴变形。熔化速率为 0.03 kg s ^{-1 时}，界面张力函数中的等效直径和滴落频率为D = 0.0119 σ ^0.23和f = 1.45 σ ^-2.37，分别。
