Symmetry and Symmetry-Breaking in Fluid Dynamics

Symmetry underlies many fluid phenomena and often provides a key to a better understanding as well as simpler analytical or numerical solutions for a variety of flows. This Special Issue of Symmetry aims to stimulate new insights and perspectives into the role of symmetry in a wide range of fluid flows, symmetry-breaking phenomena, and flows that are symmetric partially, locally, or intermittently. The following topics are included in this Special Issue: liquid drops in various settings, sedimentation of particles, viscous jets, magneto-hydrodynamic turbulence, diffusion flames, stratified flows, and propulsion in water.
