Modelling of surfactant flow dynamics in complex geometries

本项目将探索复杂几何结构界面上表面活性剂的动力学。表面活性剂是小分子，当它们的浓度梯度出现时，它们可以在界面处驱动Marangoni流。这些可以导致非常有趣的现象，如表面活性剂解决迷宫，它们对超疏水表面的减阻性能的影响，或它们在生物医学应用中的用途所示。基础非线性输运方程在许多应用中控制Marangoni流。在这个项目中，我们将寻求通过理论和数值方法模拟这些马兰戈尼流

This project will explore the dynamics of surfactant at interfaces in complex geometries. Surfactant are small molecules which can drive Marangoni flows at interfaces when gradients in their concentration arise. These can lead to very interesting phenomena as shown by surfactants solving a maze, their impact on the drag reduction properties of superhydrophobic surfaces, or their use in bio-medical applications. Underlying non-linear transport equations govern the Marangoni flows across many applications. In this project, we will seek modelling of these Marangoni flows through both theoretical and numerical approaches
