My research activities focus on non-continuum fluids engineering systems: high-speed (rarefied) aerodynamics, nano- and microfluidics, and rapid granular/gas flows. These are areas of emerging technological importance at the frontiers of engineering science.
I am investigating new ways of modelling and simulating these flows from both molecular and hydrodynamic viewpoints. In particular, developing theoretical insight into the underlying non-continuum physics, and numerical simulation tools ranging from compressible fluid codes running extended hydrodynamic models through to highly-parallel molecular dynamics and DSMC codes. All of these numerical tools are released open-source in the OpenFOAM code.
I am also developing new kinds of hybrid software that combine particle and hydrodynamic solvers under one methodology.
