Analysis of vortical structures in intermittent jets
(2016) The International Conference on Jets, Wakes and Separated Flows (ICJWSF2015) 185. p.3-10- Abstract
The manipulation of jets has since long been subject to research, due to the wide range of industrial applications in which they are used. A vast number of numerical and experimental studies concerning the physics of the breakup process of continuous jets have been published. Improvements in mixing and ambient gas entrainment have been reported experimentally when using intermittent injection, although the responsible mechanisms have not yet been completely revealed. This work presents a systematic analysis of the mechanisms of jet breakup and mixing with the surrounding fluid and its relation to vorticity generation and transport. Comparisons aremade between the redistribution of vorticity and the engulfment of ambient fluid into the... (More)

Comparisons aremade between the redistribution of vorticity and the engulfment of ambient fluid into the core region for different injection strategies.
