Vortex dynamics

Turbulence can be viewed as a manifestation of extremely complicated interactions of vortices, ranging from very large to extremely small and from intensive to much weaker, often in complicated configurations. In order to gain a better understanding of this aspect of turbulence, some of the research projects are aimed at a study of the dynamics of vortices, often in well-conditioned, idealised situations.

One of the projects concerns the dynamics of coherent vortex structures in rotating and stratified fluids. The presence of background rotation and stratification implies that flows tend to become (quasi-)two-dimensional (2D). Fundamental studies were performed on the formation of vortices (monopoles, dipoles, tripoles, ...), their stability, interaction and transport properties.
