Personal profile

Research interests

My research focuses upon the mathematical modelling of dispersed multiphase flows, with an emphasis on capturing the effects of unsteadiness or turbulence in the carrier flow upon droplets and particles.

Probability density function (PDF) models can be used to approach this, and construct a statistical description by treating the dispersed phase as a continuum. To produce closure relations that are able to account for the desired physical effects, a variety of stochastic modelling techniques are utilised. Kinematic simulation is a useful computational method which is ideal as a first test case for the developed closures.

Polydisperse droplet flows are very computationally demanding to simulate both directly and statistically, and recent work has focused upon using the Full Lagrangian Approach (FLA) to improve the efficiency of simulations. This has involved the development of novel numerical methods which use statistical learning to reconstruct a continuum representation of the dispersed phase at a reduced computational expense.

Supervisory Interests

I am interested in supervising research projects within the broad domain of modelling fluid dynamics. This encompasses both mathematical modelling to extract physical relationships that exist within flows, and numerical modelling to enable and improve the simulation of flows.

Of particular interest is the study of dispersed multiphase flows, for which the development of both numerical and mathematical models is a highly active area of research in the quest for descriptions which are both computationally efficient and accurate. A key advancement is the use of statistical descriptions for the dispersed phase which are able to account for effects experienced by individual droplets and particles, whilst maintaining the computational advantage of an averaged formulation.
