Stick-slip patterns on flat surfaces (left) lead to pressure excursions in the confined fluid when sheared against each other. The 2D (center) and centerline (right) pressure profiles are obtained using a hydrodynamics solver including a wall slip model.

Method Development for Multiscale Simulation of Lubrication

I am interested in the modeling of fluids at various scales with a special focus on application to lubrication problems, where severe loading conditions can lead to fluid films of only a few molecular diameter thickness. Hence, the lubricant's behavior is governed by molecular interaction and constitutive relations typically used in hydrodynamics lose their validity. In our project P1, I am particularly concerned with the development of tools that incorporate the molecular information into a mesoscopic hydrodynamics framework. More accurate descriptions than simple wall slip models (see Figure) for the description of the fluid-wall interface require molecular modeling.
