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

这个项目将探索表面活性剂在复杂几何形状的界面上的动力学。表面活性剂是一种小分子，当它们的浓度出现梯度时，可以驱动界面上的Marangoni流动。这些可以导致非常有趣的现象，如表面活性剂解决迷宫，它们对超疏水表面减阻性能的影响，或它们在生物医学应用中的应用。基本的非线性输运方程支配着许多应用中的Marangoni流。在这个项目中，我们将通过理论和数值方法来寻求这些Marangoni流的模型
