Development of dense gas dispersion model for emergency preparedness
Mathematical models are recognized as important tools for providing quantitative assessment of the consequences of the aeodental release of hazardous materials. In several accidental release situations, denser-than-air ...
Surface layer turbulence processess in low wind speeds over land
The atmospheric diffusion in the tropics is generally associated with low wind speeds, typically of magnitudes less than 3 m s-1. Low wind speeds would cause significant free convection in the daytime and strong stable, ...
A mathematical model for the dispersion of air pollutant in low wind condition
(Elsevier Science, 1996)
For the atmospheric dispersion of pollutants in low wind conditions, a steady-state mathemat- ical model has been formulated which takes into account the diffusion in all the coordinate directions and the advection due to ...
Comparison of sigma schemes for estimation of air pollutant dispersion in low winds
The dispersion coefficients are key parameters in most of the air quality models and their use in low wind speed conditions involves some degree of uncertainty. Various estimates of dispersion parameters are discussed for ...
Bhopal gas leak: A numerical simulation of episodic dispersion
A mesoscale meteorological model coupled with a Lagrangmn particle dispersion (LPD) model was used to simulate the Bhopal methyl isocyanate (MIC) gas leak. A simple two layer K-closure version of the Pielke primitive ...
Environmental studies of SO2, SPM and NOx, over agra, with various methods of treating calms
A comparative study between predicted and observed concentrations of major pollutants SO2, suspended particulate matter (SPM) and NOx in Agra, India has been undertaken using two Gaussian plume models. A Gaussian plume ...
