Verification of the plume rise/dispersion model USPR: plume rise for single stack emissions

Ecological Modelling, 1985
Abstract Despite proliferation of the use of air pollution models for regulatory application, major discrepancies still occur between models and also between models and observations, especially when oversimplistic models are used. The problem of predicting plume rise (and subsequently ground level concentrations) from a single source is evaluated ...

Improved estimation of CO2 emissions from thermal power plants based on OCO-2 XCO2 retrieval using inline plume simulation.

Science of the Total Environment, 2023
CO2 emissions from power plants are the dominant source of global CO2 emissions, thus in the context of global warming, accurate estimation of CO2 emissions from power plants is essential for the effective control of carbon emissions.

Stable Plume Rise in a Shear Layer

Journal of the Air & Waste Management Association, 2007
Solutions are given for plume rise assuming a power-law wind speed profile in a stably stratified layer for point and finite sources with initial vertical momentum and buoyancy. For a constant wind speed, these solutions simplify to the conventional plume rise equations in a stable atmosphere.

Buoyant plume rise in a Lagrangian framework

Atmospheric Environment. Part A. General Topics, 1992
For the dispersion of buoyant material, the interaction with the environment by entrainment forms a serious obstacle for a formulation in a Lagrangian framework. Nevertheless an outline is given here on how buoyant plume rise in a Lagrangian sense could be described.

Plume Rise Predictions

1982
Anyone involved with diffusion calculations becomes well aware of the strong dependence of maximum ground concentrations on the “effective stack height,” he. For most conditions χmax is approximately proportional to he−2, as has been recognized at least since 1936 (Bosanquet and Pearson).

Measurements of the rise of hot plumes

Atmospheric Environment (1967), 1968
Abstract Measurements of plume rise from a 76.3 m stack situated on the highveld of South Africa indicate that: 1. (I) The plume rise at 1000 m downwind is greater than that given by presently used equations. The plume shape is often scimitar-like, convex to the ground, instead of concave to the ground. It is suggested that convection effects are

The Rise of Strongly Radioactive Plumes

Journal of Applied Meteorology, 1967
Abstract The presence of radioactive gases in a plume, such as could occur in the event of a nuclear reactor accident, leads to the addition of buoyancy to the plume at an approximately linear rate. Buoyancy might also be added to plumes by chemical reactions, radiation, or latent heat exchange. The resulting plume rise is calculated by a model similar

On the rise of vertical plumes

1977
The equations expressing the conservation of mass, vertical momentum and energy are solved analytically for the rise of buoyant plumes in calm atmospheric conditions. The separate and joint effects of entrainment and drag on plume behavior are discussed.
