Characterising uncertainty in plume dispersion models

by Inderscience Publishers  (Sep. 1, 2005)

For management decisions related to effects of releases of toxic chemicals, it is useful to consider not only the expected or most likely impact of the release, but also the envelope of possible outcomes, the latter of which involves an assessment of the uncertainty in the modelling results. In this paper, we provide quantitative estimates of ...

Using plume rise schemes to model highly buoyant plumes from large fires

by Inderscience Publishers  (Feb. 8, 2011)

The atmospheric dispersion model Numerical Atmospheric-dispersion Modelling Environment (NAME) is used to simulate the smoke plume from the explosion at the Buncefield oil depot. Simple modelling, in which the plume rise is included through an effective elevated source term, captures the transport and spread of the plume well. More complex ...

The plume model MODIS: integration in the Hydro-Quebec shell

by Inderscience Publishers  (Sep. 17, 2009)

The comprehensive numerical model MODIS for the simulation of pollutant dispersion from a point source is integrated in the graphical shell of Hydro-Quebec. The shell has been developed by Hydro-Quebec to offer a valuable scheme for various applications of software products, which were originally conceived only for scientific purposes. MODIS, ...

Simulation of the plume emitted by a municipal waste incinerator in Madeira Island

by Inderscience Publishers  (Jul. 19, 2005)

TAPM (The Air Pollution Model) was applied to Madeira Island to simulate the behaviour of the plume of a municipal waste incinerator that was constructed in the southern slope of the island at an altitude of 1380 m. TAPM simulates very well the atmospheric flow that occurs around the island and inside the inner valleys under strong synoptic ...

Model comparison in simulating the atmospheric dispersion of a pollutant plume in low wind conditions

by Inderscience Publishers  (Oct. 13, 2012)

This study investigates the performance of different air pollution dispersion models in low wind conditions. The models have been applied to two sites frequently characterised by weak winds: the cities of Modena and Reggio Emilia, in the Po River Valley (Northern Italy). The emission sources are the municipal waste incinerator (Modena) and a ...

Numerical Simulations on Aerodynamics of Thermally Induced Plumes

by SAGE Publications  (Mar. 1, 2008)

Since the physics of air entrainment is not yet clearly understood, most of the fire plume expressions reported in the literature were derived empirically. Experiments with different fire geometry, fuels, and ambient conditions would be difficult when trying to derive comprehensive plume temperature and velocity fields from existing theories. ...

Comparative study of fecal bacterial decay models for the simulation of plumes of submarine sewage outfalls

by IWA Publishing  (Aug. 8, 2013)

In the literature, analytical models have been shown to be extremely useful for estimating the decay rates of coliform as fecal indicator microorganisms, providing reliable predictions of bathing conditions in coastal and continental waters. Although a number of different formulations have been developed in the literature, each one may only be ...

Large-eddy simulation and practical models

by Inderscience Publishers  (Sep. 17, 2009)

A large-eddy simulation for a point source emission has been compared with four practical dispersion models suitable for regulatory purposes, and with atmospheric measurements. The large-eddy simulation calculates the turbulent velocity field in detail and uses this to solve the conservation equation for the pollutant. The practical models are ...

Prescribed burn smoke impact in the Lake Tahoe Basin: model simulation and field verification

by Inderscience Publishers  (Dec. 30, 2013)

Smoke dispersion modelling based on the Fire Emission Production Simulator and the Hybrid Single Particle Lagrangian Integrated Trajectory (FEPS-HYSPLIT) model was applied to prescribed burns in the Lake Tahoe Basin (LTB) during fall 2011. This, in conjunction with measurements at sources and real-time ambient PM 2.5 monitoring around LTB, ...

Accounting for effects of wind rotation in the PBL on the plume characteristics

by Inderscience Publishers  (May 11, 2004)

The present work aims at demonstrating the influence of a number of dynamic effects in the PBL on the pollution concentration from a point source. The diffusion plume model applied in the study is based on the moment method. Limited number of numerical simulations, based on a more general model of a non-stationary, stratified, baroclinic PBL over ...
