My work centres around the development of understanding and mathematical models for complex multiphase 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 cerebral temperature regulation and lung function.
Multiphase (and single-phase) fluid dynamics and transport phenomena
Instabilities are at the heart of all multiphase flows - they are responsible for regime transitions and all other extraordinarily complex and seemingly chaotic flow patterns that multiphase flows demonstrate. In particular, instabilities observed on fluid-fluid interfaces (liquid-vapour) when coupled to complexities such as phase-change (evaporation/ condensation/ boiling), reactions etc.
Development of Ultra-High Resolution Multiphase Flow Solvers
My group also develops bespoke multiphase 3D flow solvers - based on the target application. For example:
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.
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.
