EFFECT OF COUPLE STRESS AND IMPACT OF CHEMICAL REACTION ON THE BEHAVIOUR OF ATMOSPHERIC AEROSOLS
The model is developed as a course of improved understanding of interactions between aerosols in the couple stress fluid. Generalised dispersion model is used to precise unsteady convective diffusion for chemically reactive pollutant in the presence of electric field. The mean concentration scattering is attained as a function of axial distance, time and couple stress `a’. The analytical results obtained for the dispersion coefficient and are illustrated by graphs for some values of electric number, couple stress parameter and reaction rate parameter. Using the obtained results conclusions are clearly depicted. It indicates that the effect of couple stress is predominating only for lesser values and the presence of chemical reaction minimises the concentration of aerosols.
