Experimental and numerical study of the dispersion of carbon dioxide plume

Journal of Hazardous Materials, 2013
Carbon Capture and Storage (CCS) and Enhanced Oil Recovery (EOR) technologies have been widely applied in the environmental protection and petroleum production fields. However, accidental release of carbon dioxide may cause damage and losses during oil and gas production.

Development of a reactive puff model for simultaneous consideration of plume dispersion and plume chemistry

Korean Journal of Chemical Engineering, 2008
To comprehensively assess and understand the environmental impacts of air pollutants emitted from large-scale point sources, the complex, non-linear photochemistry inside the plumes should be considered together with atmospheric turbulent dispersion of the air pollutants.

Line Plume and Ocean Outfall Dispersion

Journal of the Hydraulics Division, 1979
The three-dimensional flowfield created by a line plume of finite length in a steady unstratified current was investigated experimentally and theoretically. The results are applicable to ocean sewer outfall design. Even though the diffuser length may be much greater than the water depth, the flowfield cannot be considered to be two dimensional.

A Convective Plume Model for PBL Dispersion

1981
It is now clear that dispersion of air pollutants within the unstable planetary boundary layer needs to be handled somewhat differently from dispersion in less unstable conditions. This realization has come about largely on the basis of physical simulation studies by Willis and Deardorff (1974, 1976, 1978, 1979), numerical studies by Deardorff (1972 ...

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.

Plume dispersion and monitor network design

2010
Steady-state Gaussian binomial equations are widely used for predicting the dispersion and ground-level concentrations of pollutants emitted from stacks. The equations do not account for varying emissions and meteorological conditions. A pseudo-steady-state model was therefore developed by introducing a propagation time factor into the Gaussian ...

Optimisation of dispersion parameters of Gaussian plume model for CO₂ dispersion.

Environmental science and pollution research international, 2016
The carbon capture and storage (CCS) and enhanced oil recovery (EOR) projects entail the possibility of accidental release of carbon dioxide (CO2) into the atmosphere. To quantify the spread of CO2 following such release, the 'Gaussian' dispersion model is often used to estimate the resulting CO2 concentration levels in the surroundings.
