The aim of deploying hybrid nano fluids is to optimize the thermal transport characteristics of the model under study. Hybrid nano fluids incorporate composite nanopar-ticles that enhance thermal conductivity. Here, Silver(Ag) and Graphene oxide(Go) areused as nanoparticles with kerosene oil as the base fluid. The impacts of Ohmic heating, viscous dissipation, and thermal radiation are considered in order to model the problem of steady flow over a stretching/shrinking geometry. The model equations are tackled by a built-in scheme, bvp4c, in MATLAB.Moreover, there are dual solutions for a givenrange of pertinent parameters. The impact of the melting heat transfer parameter on the coefficient of skinfriction and Nusselt number for both hybrid nano fluid and nanoparticlesis considered. A comparison is established between our results and the pre-existing results, which are in good agreement. It is noted that the values of the coefficient of friction drag for the upper branch are reduced for a particular range of shrinking parameter values, while the opposite trend is observed for the lower branch. The magnetic force reduces the flow field and energy distribution for the stable branch while increasing them for the lower branch. [ABSTRACT FROM AUTHOR] |
