“…Figure 1 shows that the longitudinal diffusion coefficient K increases with increasing P for M=2Q and Sc = 20. It is interesting to note that this behavior of K with respect to the suction parameter P is opposite to that in the case of injection through channel walls as found in reference [3].…”

This paper presents an analytical solution for the dispersion of a solute in an electrically conducting fluid flowing between parallel plates with a transverse magnetic field and uniform wall suction. For fixed values of the suction parameter P and Schmidt number Sc, the longitudinal diffusion coefficient K decreases rapidly with increase in the magnetic parameter M. Further, for fixed Mand Sc, it is found that K increases with increasing P. The effect of variation of Sc on K is found to be very small.

“…It is assumed that there is uniform suction through the channel walls and a constant magnetic field acts transverse to the channel. The corresponding hydrodynamic problem was studied by Eroshenko and Zaichik [3] where there is fluid injection through the channel walls.…”
