Vortex-interface interactions in two-dimensional flows

Daniel Fuster et al.

Summary: The work focuses on the basic interactions between a vortex and an interface separating two incompressible fluids. It investigates how vorticity produced at an interface influences the dynamics of the interface and engenders small scales and small droplets. The study identifies critical Weber numbers that affect the rolling up of the interface around the vortex and trigger instabilities leading to the appearance of extremely small structures.

The generation and diffusion of vorticity in three-dimensional flows: Lyman's flux

S. J. Terrington et al.

Summary: Lyman's proposed definition of the boundary vorticity flux offers conceptual benefits in describing the transfer of circulation across a boundary, extending to three-dimensional flows, and enabling control-surface analysis. The definition also illustrates how the kinematic condition of vortex lines not ending in the fluid is maintained, providing an elegant description of viscous processes like vortex reconnection. The examination of flow over a sphere using Lyman's definition demonstrates the benefits of the proposed framework in understanding vortical flow dynamics.
