The present note deals with the effects of radiative heat transfer and free convection in MHD for a ﬂow of an electrically conducting, incompressible, dusty viscous ﬂuid past an impulsively started vertical non-conducting plate, under the inﬂuence of transversely applied magnetic ﬁeld. The heat due to viscous dissipation and induced magnetic ﬁeld is assumed to be negligible. The governing linear partial differential equations are solved by ﬁnite difference technique. The effects of various parameters (like radiation parameter 𝑁, Prandtl number Pr, porosity parameter 𝐾) entering into the MHD Stokes problem for ﬂow of dusty conducting ﬂuid have been examined on the temperature ﬁeld and velocity proﬁle for both the dusty ﬂuid and dust particles.

The paper investigates the effects of heat transfer in MHD flow of viscoelastic stratified fluid in porous medium on a parallel plate channel inclined at an angle 𝜃. A laminar convection flow for incompressible conducting fluid is considered. It is assumed that the plates are kept at different temperatures which decay with time. The partial differential equations governing the flow are solved by perturbation technique. Expressions for the velocity of fluid and particle phases, temperature field, Nusselt number, skin friction and flow flux are obtained within the channel. The effects of various parameters like stratification factor, magnetic field parameter, Prandtl number on temperature field, heat transfer, skin friction, flow flux, velocity for both the fluid and particle phases are displayed through graphs and discussed numerically.
