Abstract

Generalised dispersion of Gill and Sankarasubramanian is executed to contemplate the influence of air pollutants in a poorly conducting atmospheric fluid. The validity of time dependent dispersion coefficient and mean concentration of air pollutants are assessed with externally applied electric and magnetic field. These values are evaluated both in the presence and absence of homogeneous first order chemical reaction with porous beds peripherally. The results are attained analytically and are depicted prudently through graphs. It is perceived that in the presence of chemical reaction, the concentration of air pollutants is minimized by raising electric number, Hartmann number and porous parameter, while in the absence of chemical reaction the concentration of air pollutants is minimized by increasing the porous parameter. Better conclusions are elaborated at the end of the study.
