Nonlinear Waves and Geometric Fluid Dynamics Group

Fluid dynamics is the study of fluid motion (liquids, gases, and plasmas) and the forces exerted by the fluid on its surrounding.

Overview

Our group uses mathematical techniques such as asymptotic methods, reduced model analysis and numerical modelling to investigate fluid flows. We also use more geometric techniques such as geometric mechanics along with other geometries including differential, symplectic, Kähler, algebraic and discrete in order to describe various features of different flow systems.

Themes

Our themes range from fluid stability problems and vortex modelling on both small and large scales to the study of conservation laws and geodesic flows. Fluid dynamics applications of these research themes include predicting weather and climate systems, modelling turbulence, investigating fluid transport problems, modelling complex fluid flows and plasma modelling.

Further geometric mechanics applications are to the stability, bifurcations, dynamics and numerics of Lagrangian and Hamiltonian ODEs and PDEs, to non-Hamiltonian perturbations.

Our group includes academics who are involved in cross-disciplinary research projects such as environmental fluid flows (with the Centre for Environment and Sustainability) and data assimilation in weather prediction (with the National Centre for Earth Observation), modelling open quantum systems (with the Quantum Foundation Centre) and modelling wave fronts in crime data (with the Centre for Criminology).
