Research Interests: 

My work focuses on multi-scale fluids engineering systems: nano- and microfluidics, interfacial and other non-continuum flows, high-speed (rarefied) aerodynamics, and rapid granular/gas flows.

The engineering of flow systems across great length- and time-scales will play an important role in meeting societal challenges over the next 30 years; for example, nano-filtering seawater to make it drinkable for water-stressed populations, and embedding micro and nano devices in aeroplane and ship surfaces to improve fuel efficiency and reduce carbon dioxide emissions.

Multi-scale and multi-physics dynamics is characteristic of these areas of emerging technological importance, but affects the overall behaviour of the fluid flows in poorly-understood ways. This makes their simulation, design and control extremely difficult. The dynamics of the constituent fluid particles or molecules is key to understanding the overall flow behaviour.

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. I am also developing new kinds of hybrid software that combine particle and hydrodynamic solvers under one methodology.

All of these numerical tools are released open-source to work within the OpenFOAM code (

Specific current research includes:

  1. designs for aligned-nanotube membranes for water purification and gas separation
  2. insight into water interactions with moving surfaces, applicable to drag reduction coatings
  3. exploiting scale separation in time and space to enable efficient hybrid computations
  4. the effect of molecular mean free path variation near a surface on gas micro flows
  5. near-surface rarefaction and molecular adsorption effects on gas micro flows
  6. high-order diffusive mechanisms in gas kinetic theory
  7. using particle and molecular methods to probe flows of engineering importance

Multi-scale and multi-physics dynamics is one of the grand challenges in science and engineering for the 21st century, which means the research is long-term, complex and diverse. While there is much work still to be done, our research results show the promise of our approaches in accurately capturing the behaviour of non-continuum and non-equilibrium flows in complex geometries in a range of applications.
