Fluids

In addition to being an exceptionally rich source of problems with practical relevance to the modern world, the relatively simple concepts of fluid mechanics lead to surprisingly difficult mathematical challenges.

The fluids group acts as a focal point for activity around the broad area of fluid mechanics at Leicester. Based in the Mathematical Modelling Centre, the fluids group emphasises inter-disciplinary collaboration both nationally and internationally, and tackles problems ranging from, for example, the control of aerodynamically significant flows, to the development of efficient numerical schemes for the solution of PDEs. The collaborative nature of the group means that research is actively being undertaken using a combination of theoretical, experimental, and computational approaches.
