Effect of the plume rise and wind speed on extreme value of air pollutant concentration

Extreme values of the ground level concentration of air pollutants were evaluated as a function of plume rise deltah, and wind speed in two cases. Firstly, when a plume rise depends on the downwind distance x, and secondly, with a constant plume rise (i.e., independent on x). Also, the extreme value...

Description
Summary:Extreme values of the ground level concentration of air pollutants were evaluated as a function of plume rise deltah, and wind speed in two cases. Firstly, when a plume rise depends on the downwind distance x, and secondly, with a constant plume rise (i.e., independent on x). Also, the extreme values for the effective stack height were evaluated for different stability classes. The maximum value of the ground level concentration was obtained in unstable stability when plume rise depends on x and in the neutral stability when plume rise independent on x. Also, in stable case, the extreme values of the ground level concentration of air pollutants showed similar values in the two cases when plume rise depends on x, and with constant plume rise. Finally, it was found that the extreme value of the ground level concentration occurred near the stack and after that it was decreases in all stabilities. [PUBLICATION ABSTRACT]
