On the meaning of mixing efficiency for buoyancy driven mixing in stratified turbulent flows
(Cambridge University PressJournal of Fluid Mechanics, 2015-09-17)
The concept of a mixing efficiency is widely used to relate the amount of irreversible diabatic mixing in a stratified flow to the amount of energy available to support mixing. This common measure of mixing in a flow is ...
Inclined gravity currents filling basins: The influence of Reynolds number on entrainment into gravity currents
(AIPPhysics of Fluids, 2015-09-17)
Gravity currents of dense fluid feed basins in many important natural and industrial systems, such as lakes fed by dense rivers and auditoria supplied with cooled air by ventilation systems. The entrainment into these ...
Vortex rings impinging on permeable boundaries
(Physics of Fluids, 2015-01-17)
Experiments with vortex rings impinging permeable and solid boundaries are presented in order to investigate the influence of permeability. Utilizing Particle Image Velocimetry, we compared the behaviour of a vortex ring ...
Vortex-ring-induced stratified mixing
(Cambridge University PressJournal of Fluid Mechanics, 2015-09-16)
There is tantalizing evidence that some mechanically driven stratified flows tend towards a state of constant mixing efficiency. We provide insight into the energy balance leading to the constant mixing efficiency and ...
The synthesis of di-carboxylate esters using continuous flow vortex fluidics
(Royal Society of ChemistryGreen Chemistry, 2015-12-01)
A vortex fluidic device (VFD) is effective in mediating the synthesis of di-esters at room temperature. Processing under ambient conditions allows for a simple and efficient synthesis, whilst operating under continuous ...
