界面流变性对泡沫稳定性和油对水波的平静的重要性早已被普遍认识。最近的研究揭示了它在许多自由边界流动中的重要性，例如在蒸馏和液体萃取中。为了定量地理解这些流动，需要对界面动力学进行数学描述，本文导出了牛顿流体界面动力学的一个完全通用的公式，即其流变行为由平衡界面张力和Boussinesq [18]的两个表面粘度系数表征。考虑到表面和基体之间的密切耦合，分析最终得到两相流的界面边界条件。
The importance of interface rheology to foam stability and to the calming of water waves by oil has long been recognized in a general way. Recent research reveals its vital importance in many free-boundary flows, for example in distillation and liquid extraction. In order to understand quantitatively these flows, mathematical descriptions of the dynamics of an interface are needed.Herein is derived a completely general formulation of the dynamics of aNewtonian fluid interface, that is, one whose rheological behaviour is characterized by its equilibrium interfacial tension and Boussinesq's [18] two coefficients of surface viscosity. With consideration of the intimate coupling between surface and substrate, the analysis finally yields interfacial boundary conditions on two-phase flows.
