Dispersion of Particulate Matters from Separated Plume Stacks using Discrete Phase Modelling

Abstract

Abstract Dispersion of particulate matter from plume stacks of industries is crucial in analysing the extent of air pollution. Particulate matter is highly influenced by gravity causing it settle quickly. Dispersion of pollutants from dual plume stack separated by a certain distance is analysed here. Dual stack is effective in shielding the downstream plume causing it to spread vertically higher than single stack. PM10 particles are emitted along with gaseous pollutants from the stack in to the atmosphere having a temperature gradient of -0.2K/100 m. Particles from the stack disperse to higher distance from the ground when there is pollutant gas along with it. Furthermore, presence of discreet plumes causes splitting of the upstream one in horizontal direction causing the particles to spread more. Present study helps to monitor the spreading of particulate matter from plume stacks.
