Experimental and Computational Analysis of fluidic interfaces influenced by soluble surfactant

可溶性表面活性剂影响流体界面的实验和计算分析

基本信息

项目摘要

Surfactants are essential ingredients in many technological processes such as foaming or emulsification. Due to their amphiphilic character they assemble at fluidic interfaces and modify the respective interfacial properties. Since these interfaces are moving and are continuously deformed and expanded, the local instantaneous interfacial tension is a most relevant parameter. In order to obtain a deeper quantitative understanding of such processes with soluble surfactant, this proposal has two general objectives: By means of experimental analysis, employing tools recently developed at the Golm side, complete knowledge of basic adsorption properties for selected homologous series of surfactants at liquid/liquid interfaces will be obtained, performing studies with continuously growing drops and with transient and harmonic perturbations of drops. Since a direct measurement of surfactant distribution lateral at the interface is not possible, a numerical method for the simulation of two-phase Navier-Stokes flows with full resolution of the interface dynamics accounting for the influence of soluble surfactants is highly desired. The development of such a method is proposed here, building on recent preliminary work on the Darmstadt side. While the experimental measurements will provide the parameters required for meaningful simulations, the computational analysis will especially clarify the 3D hydrodynamics in the experiments. Together, the demanded quantitative understanding will be obtained and used to improve and validate simplified models.
表面活性剂是许多技术过程(例如发泡或乳化)中的重要成分。由于它们的两亲特性,它们在流体界面处组装并改变各自的界面特性。由于这些界面正在移动并且不断变形和膨胀,因此局部瞬时界面张力是最相关的参数。为了更深入地定量了解可溶性表面活性剂的此类过程,该提案有两个总体目标:通过实验分析,采用戈尔姆方面最近开发的工具,将获得对选定同系表面活性剂在液/液界面处的基本吸附特性的完整了解,对连续生长的液滴以及液滴的瞬态和谐波扰动进行研究。由于不可能直接测量界面处表面活性剂的横向分布,因此非常需要一种模拟两相纳维-斯托克斯流的数值方法,该方法能够完全分辨率地解释可溶性表面活性剂的影响的界面动力学。本文建议在达姆施塔特方面最近的初步工作的基础上开发这种方法。虽然实验测量将提供有意义的模拟所需的参数,但计算分析将特别阐明实验中的 3D 流体动力学。总之,将获得所需的定量理解并用于改进和验证简化模型。
