Investigation of Surface Tension Solver Based on VOF Method in Euler Meshes

摘要: 为了考察表面张力对液滴破碎的抑制作用,采用Brackbill的CSF模型,研究基于VOF界面处理方法的表面张力项离散模式. 将其用于欧拉网格中,模拟了激波和拉伸流场中液滴变形与破碎过程. 算例结果表明,Bussmann模型能够很好地解决VOF函数的表面张力离散问题.

Abstract: In order to attest that surface tension can embarrass drop deformation and breakup.CSF model is used to disperse surface tension item based on VOF method in Euler meshes. Drop deformation and breakup are simulated due to shock wave and an extensional flow. The result indicated that Bussmann model could solve dispersion problem of surface tension.
