Speaker information

Professor Gavin Esler

Understanding fluid turbulence in two dimensions has of been of interest to geophysical fluid dynamicists and plasma physicists for many decades. While it is questionable whether there exist flows in nature that are exactly two-dimensional, the small aspect ratio of the atmosphere and oceans nevertheless means that the study of idealised two-dimensional flows can reveal key aspects of the physics of more realistic systems. One such idealised model, which is simple enough to allow detailed mathematical study, consists of chaotically interacting point (i.e. very small) vortices. Can this model be used to learn anything new about real fluid turbulence?
