A Lagrangian dispersion model with chemical reactions

International Journal of Environment and Pollution, 2011
A Lagrangian stochastic (single particle) model is modified in order to account for simple chemistry reactions and tested against measured wind tunnel data. These data refers to a reactive plume generated by a single point source of NO inside a turbulent grid flow doped with ozone.

Chemical dispersants: Oil biodegradation friend or foe?

Marine Pollution Bulletin, 2016
Chemical dispersants were used in response to the Deepwater Horizon oil spill in the Gulf of Mexico, both at the sea surface and the wellhead. Their effect on oil biodegradation is unclear, as studies showed both inhibition and enhancement. This study addresses the effect of Corexit on oil biodegradation by alkane and/or aromatic degrading bacterial ...

Chemicals in the Environment, Dispersive Transport

2012
Dispersion is the enhanced mixing of material through spatial variations in velocity. When it is of interest (when we are not keeping track of the three-dimensional mixing), dispersion is typically one or two orders of magnitude greater than turbulent diffusion.

Effect of passive chemical reaction on turbulent dispersion.

AIAA Journal, 1968
As the injection velocity increases (decreasing values of m) the thermal layer is blown further away from the wall since T]T = Q(l/Pr m). For a sufficiently small value of m, the thermal layer will be far from the wall where the series expansion for / will not be valid. This value of m is found by rewriting Eq.

Development of the “Next Generation” Chemical Dispersants

International Oil Spill Conference Proceedings, 1973
ABSTRACT In order to fully appreciate the development trend for the “next generation” chemical dispersants for oil spills, the current status of this field is briefly reviewed. Recent applications illustrate the specific beneficial potential role of chemical dispersants in the oil spill control, as well as their limitation.

Atmospheric dispersion of a chemically reacting plume

Atmospheric Environment (1967), 1978
Abstract The atmospheric dispersion of a plume of pollutants, undergoing fast enough chemical reactions so that equilibrium is reached, is modelled. The effects of turbulence on the mean concentrations, due to turbulence-chemistry interactions and dispersion, are found by combining the probability density function method and the Gaussian plume model.
