Mathematical fluid mechanics for real-world flows.

We combine mathematical analysis, computation, and experiment to explain and predict flows where intuition (and standard models) fall short, from wave-driven microplastic transport to the aerodynamics of seeds.

Research overview

The Contraflow Group studies fluid mechanics across biological, interfacial, and coastal systems, with counterintuitive behaviour as the unifying theme and vortices as a recurring mechanism. Our work combines mathematical analysis, numerical simulation, and physical modelling to explain counterintuitive flow phenomena and to develop predictive tools for real-world applications.

Recent work has focussed particularly on wave-induced loading, seabed instability, and structural failure near marine and offshore infrastructure, while earlier discoveries on dandelion flight, uphill-moving droplets, and sinking bubbles revealed new mechanisms in vortex-dominated and multiphase flows.
