Concentration of air pollutants in an inclined channel with the effect of electric and magnetic field

Abstract

Background/Objectives: Atmospheric visibility is predominantly affected by aerosols and it is improved by reducing the effects of concentration of smog and haze. The model is developed suitably to study the effects of smog and haze through the concentration of aerosols in the presence and absence of chemical reactions. Methods: The atmospheric fluid in the inclined channel flow is assumed to be incompressible, laminar, and presented through the solution of Navier Stokes equation for velocity and advectiondiffusion equation for the concentration of aerosols. The governing equations of the study are attained as two-dimensional partial differential equations and are solved using the perturbation technique with appropriate boundary conditions. The solution leads to detailed graphs for velocity components and concentration of aerosols. Findings: This study examined the effects of concentration of smog and haze semi analytically in a two-dimensional channel bounded by porous beds together with the effects of the electric and magnetic field. The derived results are depicted graphically for different parameters. The obtained results of concentration clearly show that there is no considerable influence of porous, gravity and magnetic field effect in reducing smog and haze concentration, whereas the increasing electric field reduces the haze concentration.
