Abstract : The flow of a viscous incompressible fluid embedded with a small spherical particle in the presence of a transverse magnetic field in a channel has been discussed. The cross-section of the channel is a porous regular hexagonal of side 4a and the walls are non-conducting. The analysis applied to the flows with pressure gradient which are arbitrary function of time. A few particular cases, flow for impulsive pressure gradient and for constant pressure gradient have been studied. The velocity of the fluid and particle decrease with increase in the intensity of the magnetic field.

Abstract : The problem of heat transfer for the motion of a viscous incompressible fluid induced by travelling sinusoidal waves has been analytically investigated for a two-dimensional non-uniform channel. Assuming that the wavelength of the peristaltic wave, Lambda, is large in comparison to the mean half width of the channel, d, a perturbation solution in terms of the small parameter, d upon Lambda, has been obtained. Closed form expressions for velocity, temperature and coefficient of heat transfer are presented up to second order. The effects of several pertinent parameters on temperature and heat transfer have been studied and the numerical results obtained are presented.
