In modelling air pollutant dispersion, Gaussian plume dispersion equation is applied. According to this model equation, plume rise occurs immediately at the exit of industrial stack due the exit velocity of stack gas. If an obstruction is placed (such as a chimney hood), then the plume trajectory changes and the pollutants start settling in the vicinity of the industrial stack, which has a undesirable effect on pollutant dilution in ambient atmosphere.
Are there any research studies which has emphasised the effect of chimney hood on industrial plume behaviour and pollutant dispersion?
Mr.Farid, thank you for the reply. But the link consists all the air pollutant dispersion models.
Need a specific solution for the question.
Dear Shahul,
Can you clarify your question so additional help can be provided?
Air pollution dispersion models typically have a calculation of plume rise which is significant in all gaussian calculations. Critical to the plume rise calculation is the stack exit velocity and stack gas temperature. As you know, the exit velocity is reduced, or set to zero, by the presence of a chimney cap obstruction. You should read some of the background documentation for the models for a better understanding of how this situation is treated.
Good luck in your research.
