Summary: This study investigates the heat transfer characteristics of MHD hybrid nanofluid over a linear stretching and shrinking surface with suction and thermal radiation effects. The study finds that the heat transfer efficiency of the hybrid nanofluid is greater than the nanofluid, and dual solutions exist for a specific range of the stretching/shrinking parameter. Additionally, the skin friction coefficient and local Nusselt number increase with suction effect, and suction and thermal radiation widen the range of the stretching/shrinking parameter for which solutions exist.

Summary: This paper investigates the behavior of mixed convection magnetohydrodynamic flow and heat transfer induced by a nonlinear stretching/shrinking sheet in a nanofluid with a convective boundary condition using the Tiwari-Das mathematical nanofluid model. The results show that for a certain range of the stretching/shrinking parameter, two solutions are obtained, with the friction factor and heat transfer rate increasing for the upper branch solution and decreasing for the lower branch solution. The effect of nanoparticle volume fraction on heat transfer rate behaves differently in the presence of mixed convection effect, and the fluid temperature increases with increasing Biot number for both solutions.
