AB - This paper discusses the model of the boundary layer (BL) flow and the heat transfer characteristics of hybrid nanofluid (HNF) over shrinking/stretching disks. In addition, the thermal radiation and the impact of velocity and thermal slip boundary conditions are also examined. The considered hybrid nano-fluid contains silver (Ag) and iron oxide (Fe3O4) nanoparticles dispersed in the water to prepare the Ag-Fe3O4/water-based hybrid nanofluid. The requisite posited partial differential equations model is converted to ordinary differential equations using similarity transformations. For a numerical solution, the shooting method in Maple is employed. Moreover, the duality in solutions is achieved for both cases of the disk (stretching () and shrinking ()). At the same time, a unique solution is observed for = 0. No solution is found for them at , whereas the solutions are split at the . Besides, the value of the is dependent on the . Meanwhile, the values of and intensified with increasing . Stability analysis has been applied using bvp4c in MATLAB software due to a dual solution. Furthermore, analysis shows that the first solution is stable and feasible physically. For the slip parameters, an increase in the velocity slip parameter increases the velocity and shear stress profiles while increasing the temperature profile in the first solutions. While the rise in thermal slip parameter reduces the temperature profile nanoparticle volume fractions increase it.
