Explore the intricate relationship between droplets and vortices in this 41-minute conference talk delivered by Rama Govindarajan at the International Centre for Theoretical Sciences. Delve into the complex world of turbulent fluid flow, spanning from quantum mechanical to cosmological scales. Examine the droplet growth bottleneck, dynamics near point vortices, boundary layer structures, and singular perturbation problems. Discover where droplets live, how collisions occur, and how they evacuate the neighborhood of vortices. Investigate the evolution of droplets with phase change and the interplay between inertia, thermodynamics, and buoyancy. Gain insights into vortex pair mechanisms and how buoyancy affects dynamics in turbulent systems. Conclude with a summary and participate in a Q&A session to further explore this fascinating topic in fluid dynamics.
