Recent studies on the flow phenomena in stratified thermal-energy-storage (TES) systems
have shown that heat conduction from the hot upper fluid layer through the vertical tank …

The effects of an inlet inertial jet on the thermal blending of hot and cold heat transfer fluid
(molten salt) for a single tank sensible thermal energy storage system are studied using …

The demand for renewable energy sources is limited by their inherent intermittent nature.
The thermal energy storage technique overcomes this shortcoming by allowing storage of …

Toroidal bubbles (TBs) represent cases of vortex rings with a gas–liquid interface where a
gas vortex ring is encased within a liquid vortex ring, and can serve as effective media for …

The vortex dynamics in a stratified environment is of fundamental importance in various flow
systems, however, the mechanism of successive vortex–interface interactions remains not …

Inspired by recent studies of a squid-like swimmer, we propose a three-dimensional jet
propulsion system composed of an empty chamber enclosed within a deformable body with …

We experimentally investigate the transport of liquid by a toroidal bubble that rises vertically
and penetrates a horizontal interface between two immiscible liquids. Experiments 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 …

Flow transitions and vortical developments during vortex-ring collisions with a sharp water–
oil density interface are studied using planar laser-induced fluorescence and time-resolved …

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 …
