Modeling the dynamics of slippery surfaces
A close interaction between modeling and experiment will be very important to fully understand and exploit the interaction of fluids with structured surfaces. LubISS aims to integrate modeling across all length scales to investigate properties that range from the detailed behaviour at the contact line to the way in which fluid films move across the designed substrates.
The DPhil (= Oxford PhD) student employed on this project will play a pivotal role by developing multiphase lattice Boltzmann simulations to model flow over the structured surfaces. We will need to determine how to include several coexisting phases, and how to model the viscoelastic properties of the lubricants. The codes will be used to consider the ability to repair surfaces by wicking, assess the dependence of lubricant stability on substrate geometry, and consider splashing and the consequent lubricant removal caused by droplet impact. The direction of the project will also depend on close interactions with other members of the LubISS team.
The position requires:
- An interest in computational physics.
- Strong analytic ability, as evidenced by eg an excellent first degree in physics, mathematics or a related subject.
- A willingness to contribute fully to the scientific interactions of the network.
