Research interests

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.

 Animations from my research

CFD simulation of bubble release from a cavity during boiling of liquid sodium - temperature distribution around the bubbles: blue = cold, red = hot.
CFD simulation of pool boiling from a cavity in a pool of liquid sodium, using a novel method for capturing interfacial mass transfer implemented in the OpenFOAM code. Animation of phase distribution field - blue = sodium vapour, red = liquid sodium.
