Research Expertise/Interests

Development of optimally efficient multilevel/multigrid numerical solution algorithms for applications in
engineering (e.g. fluid mechanics, structural mechanics, acoustics, and lubrication) and physics (MD simulations). (Systems of) partial differential equations, integral equations (Fredholm), integral transforms with smooth, asymptotically smooth, and oscillatory kernels, and long range force computations in particle simulations.

Thin layer flow problems, in particular related to elastohydrodynamic lubrication (EHL). This is the predominant type of lubrication in rolling element bearings, cam-followers, between gear teath and in human (artificial) joints. Modeling and simulation (prediction) of in-contact behaviour, and of the free surface thin layer flow around the contact under all conditions, fully flooded, starved, and mixed lubrication, including time dependent effects of loading conditions and surface roughness passing through the contact and lubricant migration. Experimental research using optical interferometry on single contact for model validation.
