The present discussion deals with the study of an unsteady flow and heat transfer
of a dusty fluid through a rectangular channel under the influence of pulsatile pressure
gradient along with the effect of a uniform magnetic field. The analytical solutions of the
problem are obtained using variable separable and Fourier transform techniques. The graphs are
drawn for the velocity fields of both fluid and dust phases under the effect of Reynolds number.
Further, changes in the Nusselt number are shown graphically, and, on the basis of these,
the conclusions and discussions are given.
