Dynamics of downdruaghts and cold pools: an experimental and numerical study
… filled with sodium nitrate solution which was dyed using methylene blue. The fluid was released by bursting the latex sheet and was analysed using an extension to the dye attenuation technique developed by Cenedese & Dalziel (1998). Red, green and blue LEDs were used to address the need for a …

Turbulent entrainment in flows induced by distributed buoyancy sources
… ambient stratification was measured using dye-attenuation with an LED-light bank for varying buoyancy fluxes and ventilation flow rates.

Filling flows induced by a convector in a room
… involve a combination of a shadowgraph method, a dye-attenuation method, direct salinity measurements and a new application of Particle Image Velocimetry (PIV). Interesting insight into convector-induced buoyancy-driven flows has been gained. As a result, new guidelines aimed at heating rooms more …

The influence of buoyancy upon near wake pollutant dispersal
… and concentration profiles were found using dye attenuation. For a neutrally buoyant exhaust released into the wake of a backward-facing step, pollutant is well mixed into a region extending to 𝑥/𝐻 ∼ 2 and approximately the height of the step. Introducing buoyancy pushes the pollutant into a …
