In the current study, we have considered the impact of inclined magnetic …eld and metallic nanoparticles on the peristaltic ‡ow of nano‡uid in an annulus with convective boundary conditions. The impact of emerging parameters on ‡ow quantities are described via graphs. Some crucial observations of the present analysis are mentioned as, Signi…cant addition of Cu and Ag nanoparticles increases the heat transfer rate in the existence of Biot number. Pro…les of velocity exhibit higher results for silver blood than for the copper blood and pure blood. The velocity pro…le reduces when we strengthen the applied magnetic …eld. It is observed that the velocity increases for convective parameter. Pressure gradient increases with increasing nanoparticle volume fraction. In retrograde pumping region, the pressure rise enhances for Biot number. Pressure rise enhances due to the impulsion of metallic nanoparticles when compared to that of the pure blood ('' = 0:00): Silver and copper nanoparticles show opposite behavior on the number of trapped bolus. Trapping phenomenon show that the circulating bolus increases as we consider the horizontal to the vertical annulus case.
