| Summary: | Exact analysis of miscible dispersion of solute with interphase mass transfer in a poorly conducting couple
stress fluid flowing through a rectangular channel bounded by porous layers is considered because of its
application in many practical situations. The generalized dispersion model of Sankarasubramanian and Gill is
used, which brings into focus the exchange coefficient, the convective coefficient and the dispersion
coefficient. The exchange coefficient comes into picture due to the interphase mass transfer and independent
of solvent fluid viscosity. It is observed that the convective coefficient increases with an increase in the
porous parameter while it decreases with an increase in the couple stress parameter. The dispersion
coefficient is plotted against wall reaction parameter for different values of porous parameter and couple
stress parameter. It is noted that the dispersion coefficient decreases with an increase in the value of couple
stress parameter but increases with porous parameter.
