Detrainment of plumes from vertically distributed sources
(SpringerEnvironmental Fluid Mechanics, 2016-11-22)
We present experimental results demonstrating that, for the turbulent plume from a buoyancy source that is vertically distributed over the full area of a wall, detrainment qualitatively changes the shape of the ambient ...
Ten questions about natural ventilation of non-domestic buildings
(ElsevierBuilding and Environment, 2016-10)
Throughout history, natural ventilation has remained the preferred choice for the majority of residential buildings, while, in commercial buildings, natural ventilation went from being the single option to somewhat of a ...
Impact of aperture separation on wind-driven single-sided natural ventilation
(ElsevierBuilding and Environment, 2016-11-01)
This paper presents a study of the impact of horizontal aperture separation in single-sided ventilation flows with two apertures (SS2). The study is based on wind tunnel measurements and dimensional analysis. The results ...
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 ...
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 ...
