The Deformation and Rupture of Thin Liquid Films

基于边界积分法的数值模拟将应用于重力、表面张力和剪切作用下液膜稳定性的研究。薄膜将被认为是高粘性的，而通常的简化近似，即假定薄膜厚度变化发生在波长比薄膜厚度大得多的情况下，将不必使用。在表面变形变得非常大的情况下，用数值方法跟踪薄膜不稳定性的发展。该研究涉及涂层、润滑和泡沫等薄膜技术中的现象。

Numerical modeling based on the boundary integral method is to be applied to the study of liquid film stability under the action of gravity, surface tension, and shear. The films will be considered as highly viscous, and the usual simplifying approximation, whereby film thickness variations are assumed to occur with wave lengths much larger than the film thickness, will not have to be used. The development of film instabilities will be followed numerically into the regime where surface deformation has become very large. The research is relevant to phenomena in film technologies such as coating, lubrication, and foams.
