Abstract

Abstract: The current article explores the effect of viscous dissipation on the hybrid nanofluid flow over a stretching sheet. Further, different nanoparticles can be used to enhance the thermal conductivity of the fluid. The resultant suspension is examined with the effect of velocity slip. The velocity slip effect is incorporated in the boundary condition of the momentum equation. Heat transfer analysis is done in presence of convective conditions and thermal radiation. Comparative study of different hybrid nanofluids and nanofluid is considered. Here we have chosen manganese Zinc ferrite MnZnFe2 O4 and Nickle Zinc ferrite NiZnFe2 O4 as nanoparticles in base fluids Kerosene oil and engine oil. Mathematical modeling of the present flow system is illustrated and solved by the shooting built-in method. Graphs for velocity, temperature, skin friction and Nusselt number are presented for different parameters. Here we noticed that velocity profile of MnZnF e 2 O 4 − NiZnF e 2 O 4 − C 1 0 H 2 2 − C 8 H 18 is maximum as compared to other hybrid nanofluids. Velocity and temperature have opposite effects against slip parameter. The temperature of the fluid rises with Biot number and thermal radiation.
