The effect of suspended particles on thermal instability of a viscoelastic Walters' (model B') fluid in the presence of a uniform horizontal magnetic field is considered. The sufficient conditions for non-existence of overstability are found in the presence of horizontal magnetic field. The effect of suspended particles is to postpone the onset of convection. For stationary convection, Walters' (model B') viscoelastic fluid behaves like a Newtonian viscous fluid.Keywords

The paper investigate the effect of heat and mass transfer in radiating and chemically reacting MHD oscillatory flow of viscoelastic fluid [Walter liquid model B] in a vertical channel with slip condition on one plate of the channel. The uniform magnetic field Bo is applied perpendicular to the planes of the plates. A closed form solutions of the equations governing the flow are obtained for the velocity, temperature and concentration profile. The velocity, temperature, and concentration profiles as well as skin friction coefficient and mass transfer rate are evaluated numerically and presented graphically for different value of flow parameters.
