Vortex interactions with flames play a key role in many practical combustion applications.
Such interactions drive a large class of combustion instabilities, they control to a great extent …

The present study involves the shock wave and consequent vortex loop generated when a
shock tube with various nozzle geometries is employed. It aims to provide quantitative and …

The results of experiments performed to study the linear phase of the instability of vortex
rings are presented. The experiments were performed in water. The vortex rings are …

The evolution of vortex rings in isodensity and isoviscosity fluid has been studied analytically
using a novel mathematical model. The model predicts the spatiotemporal variation in peak …

Flapping flight is one of the most costly forms of locomotion in animals. To limit energetic
expenditures, flying insects thus developed multiple strategies. An effective mechanism to …

The starting flow fields produced by a supersonic underexpanded planar jet are studied
numerically with the use of large eddy simulation (LES). The three-dimensional (3D) …

We investigate the cleaning mechanism of an oil-impregnated porous surface by utilizing a
method of vortex ring interaction. The kinetic energy of a vortex ring is exploited to expunge …

The focus of the current study is to examine experimentally the diffracted shock wave pattern
and the consequent vortex loop formation, propagation, and decay from nozzles having …

Flow and acoustic characteristics of high Mach number compressible vortex rings have been
investigated in this thesis. Features associated with formation and evolution of vortex rings …

We describe a model of the nuclear cloud in terms of the vorticity field associated with a
buoyant vortex ring. A series of physical approximations are introduced that lower …
