Abstract

Vortex rings are ubiquitous in nature as well in man-made devices such as starting jets and synthetic jets. Recently, useful applications of such flow structures in industry have been proposed that involve motion of vortex rings over an axially placed rod. Although free vortex rings are quite stable and propagate for long distances without disintegrating, the scenario is modified to a great extent in presence of such an interacting body. Thus, in the present study, we study their properties and robustness of vortex rings produced from an orifice, with an axial rod aligned symmetrically with respect to its direction of propagation. We find the effect of such vortex body interaction, with the help of flow visualizations, which reveals the extent of their sustainability under the given conditions.
