Abstract
Hybrid nanofluids enhance heat transfer and thermal conductivity in various applications, from electronics cooling to solar energy collection. They offer energy efficiency benefits and can reduce material usage. Their use spans multiple industries, including electronics, energy, and medical treatments.In this paper we study theoretically the analysis of heat transfer on MHD hybrid nanofluid flow over a permeable stretching surface in a porous medium with variable viscosity and other physiochemical properties for detailed interpretation and usefulness of the fluid flow parameters in modelling. Uniform magnetic field is applied together with heat source and sink. Three set of different hybrid nanofluids with water as a base fluid having suspension of copper-Aluminium Oxide , Silver-Aluminium Oxide and copper-Silver nanoparticles are considered. The maragoni boundary conditions applied. The governing models of the flow is solved by Runge-Kutta fourth order method with shooting technique, using appropriate similarity transformations. Temperature and velocity field are explained by the figures for many flow pertinent parameters. Almost same behavior is observed for all the parameters presented in this analysis for the three set of hybrid nanofluids. It was also observed that Radiation, Heat source/Sink and Local temperature difference has no significant impact on the velocity profile. Also increase in mass transfer wall decreases both the velocity and temperature profile. Hence all the embedded fluid flow parameter of the hybrid nanofluid has greater influence on the skin friction, nusselt number and the thermal boundary layer.
