Research Interests: 

Development of Ultra-High Resolution Multiphase Flow Solvers

My group also develops bespoke multiphase 3D flow solvers - based on the target application. For example:

  1. TPLS Flow Solver (V2 Opensourced in May 2015) - For two layer (fluid/fluid) flows - for oil/gas or oil/water flows, gas/liquid flows in absorption or distillation units, or for phase change flows for thermal management of microdevices.
  2. GISS Flow Solver (soon to be opensourced) - DNS solver for immersed solids in flows - for slurry flows such as hydrate agglomerates or large complex-shaped solids immersed in flowing fluids.

These solvers are optimised for supercomputing clusters such as ARCHER.

Summary description of my work

My work centres around the development of understanding and models for complex flow patterns to tackle various industrial problems like cleaning, oil-gas transport, slurry transport, distillation, absorption, thermal management of microdevices and biological problems such as deposition of plaque in arteries and growth of cancerous tumours

Multiphase and single-phase fluid dynamics and transport phenomena

Process design and intensification Biological fluid dynamics and material science

Hydrodynamic stability and turbulence

I am particularly fascinated about instabilities in multiphase flows.

Multiphase Flows

You can watch this video on Media Hopper or on YouTube.

Specialities: 

  • Transport phenomena (e.g. phase change, reaction-diffusion transport)
  • Multiphase (& single phase) fluid dynamics: Development of numerical (CFD/DNS) and analytical (stability theory) tools (e.g. oil-gas-solid pipeline flows, industrial cleaning and fouling)
  • Biological fluid dynamics (e.g. brain temperature mapping, arterial flows, enzymatic kinetics)
