Research Projects
Bubble dynamics and tomography of bubbling beds
Simulations of single and interacting bubbles in liquids and thin columns, and electrical capacitance volume tomography (ECVT) to measure bubbles in fluidized beds.
Droplet impact and evaporation on hot surfaces
Experiments and simulations of droplets hitting, spreading on and evaporating from hot surfaces and particles, including film boiling above the Leidenfrost temperature.
Hydrodynamics of FCC risers, strippers and catalyst circulation
CFD and gamma-ray measurements of the gas-solid flow in fluid catalytic cracking units, and tests of baffles and pulsating flow to make them perform better.
Modelling fluidized bed polymerization reactors
Reactor models linking polymerization kinetics, particle size distribution and condensed-mode operation in fluidized bed polypropylene reactors, plus jet fluidization experiments and CFD.
Multiscale modelling of gas-solid flow and drag
Lattice Boltzmann simulations of particle clusters, energy-minimisation multiscale (EMMS) drag models and closure studies that make CFD of risers and fluidized beds more predictive.
LNG ambient air vaporizers: heat transfer, fog and frost
CFD models of how ambient air vaporizers warm cryogenic LNG, how they make fog and frost, and how LNG vapour disperses, to support safer design and siting.
Intensifying multiphase reactions and reactors
Strategies and worked examples for making gas-liquid and gas-solid reactors smaller, safer and more productive, from 3D-printed distributors to retrofit reactor inserts.
A novel settling tank for produced water treatment
A settling tank with no moving parts that uses a swirling inlet flow to separate fine particles from produced water, developed with CFD and validated by PIV.
Gas-liquid and solid-liquid stirred tanks
CFD and optical-probe measurements of how stirred tanks suspend solids and disperse gas, from dilute to dense slurries, and from baffled tanks to unbaffled vortices.
SpiroPak: 3D-printed structured packing
A spiral structured packing designed for additive manufacturing, with CFD and experiments on how packing geometry sets pressure drop and liquid distribution.
