Fluid Dynamics and Thermal Systems


Our group is engaged in a wide range of research work. This covers analytical, computational and experimental investigations of both fundamental and industrial problems of heat, mass and momentum transport.

We have cutting-edge expertise in a number of key areas of thermo-fluid mechanics. Our contributions to the relevant areas of research have been internationally significant over the years.

The Sir Joseph Swan Centre for Energy Research, now based in the School, is linked to Fluid Dynamics and Thermal Systems research.

Research expertise

Our research expertise covers a good mix of fundamental physical investigations and applied industrial research.

We have an excellent computational and experimental infrastructure for supporting these research activities. We also have experience in developing in-house CFD codes for fundamental physical investigations and using the common commercial packages for industrial applications.

Key areas of research include:

PDF models for disperse turbulent multiphase flows

Our research in this area includes:

  • closure methods
  • boundary-layer treatments
  • added-mass modelling
  • particle deposition and re-suspension
  • particle-fluid interactions
  • Brownian motion

Turbulent multiphase flow applications

Our research in this area includes:

  • atmospheric aerosol transport
  • particle transport processes in nuclear reactor cooling circuits and containment systems
  • particle deposition on heat exchanger tube arrays
  • transport and deposition in the human respiratory tract
  • droplet and particulate transport in oil pipe-line systems

Reducing NOx emissions

Miller cycle application to reduce NOx emissions from petrol and diesel engines, and flameless oxidation to reduce NOx emissions from power plant/gas turbine.

Direct Numerical Simulations of turbulent reacting flows

Our research in this area includes turbulent premixed, non-premixed, partially-premixed and stratified flames, and droplet-laden combustion.

Modelling of turbulent combustion

Our research in this area is in the context of Reynolds Averaged Navier Stokes (RANS) and Large Eddy Simulations (LES) using DNS data.

Other areas of research

Other areas include:

  • turbulent heat and mass transfer in solid-liquid phase change problems
  • natural convection of complex non-Newtonian fluids
  • Computational Fluid Dynamics (CFD) modelling of single and multi-phase flows
