建立了一种新的液滴破裂模型。在该模型中，结合多重破碎和底层湍流，提出了几种有效的表面能密度增加约束条件。它们表现出对原始液滴大小和子液滴大小的依赖，并反映了二元和高阶破裂之间的差异。子液滴大小之间可能的不可交换性取决于破碎过程。同时，它可以用所提出的约束来解释。该模型预测的破碎率和子代尺寸分布与文献报道的现有实验数据吻合良好。(C) 2013 Elsevier Ltd.版权所有。
A novel model for droplet breakage has been developed. In this model, several effective constraints of surface energy density increase combining the multiple breakage and the underlying turbulence were proposed. They exhibit a dependency on the original droplet size and the daughter droplets sizes, and reflect the difference between binary and higher order breakages. The possible non-exchangeability among the sizes of daughter droplets depends on the breakage process. Meanwhile, it can be accounted for by the proposed constraints. The breakage rate and daughter size distributions predicted by this model showed a good agreement with the available experimental data reported in the literature. (C) 2013 Elsevier Ltd.
