Plume Rise in a Shear Layer with Neutral Stability
Journal of the Air & Waste Management Association, 2005Several solutions have been published to predict the rise of buoyant plumes in a shear layer with a power-law velocity profile. Each of these solutions is either a special case or is based on oversimplifying assumptions. In this paper, solutions to the plume-rise equations are given for buoyant and nonbuoyant plumes with initial vertical momentum ...

The Applications of an Integral Plume Rise Model
1984The mathematical description of plume rise is well established and has been reviewed by Briggs1. As the ground level concentration of pollutants is a strong function of the effective rise of the plume above the chimney, Δh, it is important that this quantity can be calculated over a wide range of meteorological conditions.

The Validity of Several Plume Rise Formulas
Journal of the Air Pollution Control Association, 1969The ground level concentration of pollutants downwind of a tall chimney decreases as the effective height of the stack increases. The effective height of the stack is the actual height plus the rise of the plume center-line due to momentum and buoyancy of the effluent.

Buoyant plume rise in atmospheric inversions
International Journal of Heat and Mass Transfer, 1977Abstract The rise of a buoyant plume into atmospheric inversions is investigated analytically for a range of inversion rates. The analysis assumes gaussian distribution of velocity and temperature. The results show that maximum plume rise decreases with inversion intensity, and the ratio of maximum rise to the height at which zero buoyancy occurs is ...

Particle fallout during plume rise
Atmospheric Environment (1967), 1982Abstract The criterion for gravitational separation of particulate matter from a rising plume is discussed and theoretical calculations of the associated separation trajectories are made using line thermal flow data. The threshold for separation is shown to be dependent upon the position at which the particle leaves the plume, fallout occurring more ...

The prediction of the rise of cooling tower plumes
Atmospheric Environment (1967), 1974Abstract An expression developed from the chimney plume trajectory equation (Moore, 1974) is shown to give a good representation of some limited experimental data on cooling tower plumes at Eggborough. The heat emission term is taken as that from a single tower. Account is also taken of the relatively small temperature difference between the effluent

A Plume Rise Model Compared with Observations
Journal of the Air Pollution Control Association, 1965Dimensional arguments are used to predict plume rise for buoyant plumes in both stable and neutral air, for both calm and windy conditions. Dominant terms are assumed to be windpseed ū, “buoyancy flux” F (proportional to heat efflux), and a stability parameter s (proportional to potential temperature gradient).

Dilution in Transition Zone between Rising Plumes and Surface Plumes [PDF]
, 2004 The papers presents some physical experiments with the dilution of sea outfall plumes with emphasize on the transition zone where the relative fast flowing vertical plume turns to a horizontal surface plume following the slow sea surface currents. The experiments show that a considerable dilution takes place in this zone depending on the ratio between ...
