Effects of polymer and dust particles inclusion on drag and heat transfer characteristics in Non-Newtonian dusty fluids

Abstract

The objective of this article is to examine the simultaneous incorporation of polymers and dust particles, a previously unexplored topic according to the available literature. Understanding these effects is essential for industrial processes and biomedical engineering applications where the manipulation of drag and heat transfer characteristics is desired. This research looks at how including polymers in a viscous non-Newtonian FENE-P dusty fluid alters the flow and heat transfer characteristics of the boundary layer over a non-linearly stretched surface. By employing an appropriate similarity transformation method, we transform the nonlinear system of equations into an equivalent form that exhibits similarity. The resulting boundary layer equations are then numerically solved to investigate the effect of flow factors on the drag force and Nusselt number. This analysis allows us to investigate how various flow parameters influence the forces experienced by the fluid and the rate of heat transfer. In our investigations, we observe a decrease in velocity and an increase in heat transfer when both polymers and dust particles are present. These results suggest that the presence of polymers and dust particles simultaneously has a positive effect on fluid dynamics and increases the system’s thermal exchange efficacy.
