Direct numerical simulation of free surface systems

The main focus of my work is to developing numerical techniques for the direct numerical simulation (DNS) of multiphase flows. My current focus is on the use of the projection method, levelset formulation for implicit interface tracking, pseudo-spectral methods, and iterative methods (e.g. for the solution of the variable coefficient Poisson equation with high density contrast). The main application of this work is to perform DNS in turbulent free surface flows. In particular, I simulate falling liquid films and develop LES and RANS models from the DNS database. The computational challenges posed by these problems, require development of codes that run on distributed memory parallel machines (clusters). To this end the group is also developing Flat Network Neighbourhood (FNN) Clusters
