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.
