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?
