Abstract : This theoretical investigation is aimed at finding the influence of the cross-section on the equivalent dispersion coefficient of a solute in a non-Newtonian medium flowing through a channel by considering the Power law, Bingham plastic, Casson models of fluids and it has been noted that in the case of the first two, there is a steep rise with the increase of the width of the channel, but in the case of Casson model, equivalent dispersion coefficient attains a maximum at R/a = 1.7. Some explanation is offered for this behaviour of the fluids.
