The fluxes and behaviour of plumes inferred from measurements of coherent structures within images of the bulk flow
(Taylor & FrancisAtmosphere - Ocean, 2016-06-01)
This paper describes how measurements of the movement of identifiable features at the edge of a turbulent plume can be interpreted to determine the properties of the mean flow and consequently, using plume theory, can be ...
Questioning the Mpemba effect: hot water does not cool more quickly than cold
(Nature Publishing GroupScientific Reports, 2016-11-24)
The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect ...
Mixing efficiency in run-down gravity currents
(Cambridge University PressJournal of Fluid Mechanics, 2016-12-25)
This paper presents measurements of mixing efficiency of the two counter-flowing gravity currents created by symmetric lock exchange in a channel. The novel feature of this work is that the buoyancy Reynolds number of the ...
Conditional sampling of a high Péclet number turbulent plume and the implications for entrainment
(Cambridge University PressJournal of Fluid Mechanics, 2017-07-25)
We present simultaneous two-dimensional velocity and scalar measurements on a central vertical plane in an axisymmetric pure turbulent plume. We use an edge-detection algorithm to determine the edge of the plume, and compare ...
The Modular Aerial Sensing System
(American Meteorological SocietyJournal of Atmospheric and Oceanic Technology, 2016-06-01)
Satellite remote sensing has enabled remarkable progress in the ocean, earth, atmospheric, and environmental sciences through its ability to provide global coverage with ever-increasing spatial resolution. While exceptions ...
The effects of an opposing buoyancy force on the performance of an air curtain in the doorway of a building
(ElsevierEnergy and Buildings, 2015-06-01)
We investigate the effects of an opposing buoyancy force on the performance of an air curtain in the doorway which separates a warm indoor environment from the cold exterior. Such an opposing buoyancy force arises for ...
