Velocity of An Axisymmetric Vortex Ring

Advisor: Arkadi Berezovski, Ph.D., Senior Researcher at Institute of Cybernetics

Background

A stable laminar vortex ring is formed when an axisymmetric impulse is imparted on a fluid. The laminar vortex ring is one of the most fundamental of the canonical flow fields used in the study of vorticity dynamics, and the simple structure of the ring lends itself sell to both experimental and theoretical investigation. In the same sense the ring provides a simple flow field, simultaneously accesible to experimental, numerical and theoretical study, in which understanding of the molecular mixing process in fluid flows can be meaningfully examined and extended. Interestingly, previous experimental studies have shown that certain aspects of vortex ring formation and propagation differ markedly from their classical descriptions based on potential flow models.
