我们研究了最近提出的密度缩放平衡CSF（连续表面力）模型与水平集曲率插值技术。将密度尺度平衡CSF模式与基于CLSVOF（耦合水平集和流体体积）方法、THINC/WLIC（双曲线切线界面捕获/加权线界面计算）方案、多矩方法（CIP-CSL R和VSIAM 3）的数值框架相结合。本CSF模型检查各种基准问题，如滴-滴碰撞和滴飞溅。与实验观测结果和其他CSF模型的比较表明，本CSF模型可以最大限度地减少虚假电流和捕获复杂的流体现象，最小化漂浮物。
We examine the recently-proposed density-scaled balanced CSF (continuum surface force) model with a level set based curvature interpolation technique. The density-scaled balanced CSF model is combined with a numerical framework which is based on the CLSVOF (coupled level set and volume-of-fluid) method, the THINC/WLIC (tangent of hyperbola for interface capturing/weighted line interface calculation) scheme, multi-moment methods (CIP-CSLR and VSIAM3). The present CSF model is examined for various bench mark problems such as drop-drop collisions and drop splashing. Comparisons of the present model results with experimental observations and those from the other CSF models show that the present CSF model can minimize spurious current and capture complicated fluid phenomena with minimizing floatsam.
