Research interests

I am interested in numerical modelling of heat transfer and fluid flow, in particular multi-phase flow with phase change and boiling heat transfer, and in the development of interface-capturing CFD techniques for simulation of industrial two-phase flows on arbitrary geometries using unstructured meshes.

My current research focuses on wettability and phase-change phenomena at solid surfaces and is sponsored by the UK Engineering and Physical Sciences Research Council (EPSRC) under fellowship grant 'Modelling surface effects in two-phase fluid processes across scales'.
