Abstract

The book offers a guide to understanding models of vortex rings, starting from classical ones (circular vortex filament, Hill and Norbury-Fraenkel inviscid models) to very recent models incorporating viscous effects and realistic shapes of the vortex core. Unconfined and confined viscous vortex rings are described by closed formulae for vorticity, stream function, translational velocity, energy, impulse and circulation. Models are applied to predict the formation number of optimal vortex rings and to describe two-phase vortex ring-like structures generated in internal combustion engines. The text provides a detailed presentation of analytical developments of models, backed-up by illustrations and systematic comparisons with results of direct numerical simulations. The book may be used by graduate students in applied mathematics, engineering and physical sciences. It could be a useful reference for researchers and practising engineers interested in modelling flows with vortex rings.
