My general area is the mathematical and computational modelling of fluid dynamics. In particular, I am interested in the free surface flow problem or interface between two-layer fluids, especially the mathematical 'singularity' problem upon the topological change at the free surface, and also the dispersed multi-phase flow. The current project is implementing Fully-Lagrange Approach(FLA) into OpenFoam to study the polydisperse spray into gas, including the effects of vaporation and also two-way coupling.
