Research Overview

I am particularly interested in the following three research areas: the dynamical systems interpretation of fluid flow, the categorisation of environmental mixing events, and the modelling of non-Newtonian fluid processes including compressible and reactive porous media.

Dynamical Systems and Computational Fluid Mechanics
  • Designing control schemes to guide turbulent flows towards energy-efficient low-drag states.

  • Analsysing critical trajectories in state space that transition to turbulence in oscillating flows.

  • Understanding the effect of oscillations on structures embedded in chaotic dynamical systems.

Environmental Flows – Computation and Analysis
  • Direct numerical simulation of environmental flows, including ocean and estuarines mixing.

  • Developing diagnostics to analyse mixing events, using underlying conservation laws.

  • Analysing coherent nonlinear structures and waves in stratifies shear flows.

Non-Newtonian Modelling of Industrial and Environmental Fluid Processes
  • Thixotropic modelling and simulation of concrete pumping, for industrial benchmarking.

  • Modelling of natural estuarine sediments and industrial compressible porous media.

  • Migration of salt through sea-ice into overlying snow as a reactive porous medium.
