The wetting behaviour of liquids on solid surfaces plays an important role for current and emerging technologies involving liquids from the nano- to the macro-scales. These technologies are useful for numerous industrial applications, such as in oil recovery, microfluidics, heat transfer, lubrication and coatings. They can also underpin possible solutions to many of United Nations’ sustainable development goals, including on the issues of clean water, sustainable cities, responsible consumption and production.
Inspired by nature, especially by the extraordinary surface properties of insects, animals and plants, a biomimetic strategy that has proved very powerful for controlling surface wettability is by structuring the surface. In particular, for this project, we will study a novel type of liquid repellent surfaces inspired by pitcher plants, whereby rough or porous materials are infused with lubricants . These so-called liquid infused surfaces can exhibit a number of advantageous surface properties, including self-cleaning, drag reduction, anti-icing and anti-fouling.
This project aims to study the rich wetting dynamics of liquid droplets on liquid infused surfaces, in order to provide insights into advantageous surface properties of liquid infused surfaces. The student will develop and use computer simulations based on the lattice Boltzmann method [2,3], taking advantage of the group’s recent progress in modelling multiphase and multicomponent flows in complex geometries. Depending on the interests of the student, the project can also involve substantial analytical work. This project will involve collaborations with our experimental and industrial partners.
