Heat Transfer Analysis of Casson Hybrid Nanofluid Flow Through Porous Convergent-Divergent Channels with Silicon Oil as Base Fluid

In this research article we investigate rate of heat transfer of magneto hydrodynamic MHD flow of casson hybrid nanofluid silicon oil through porous convergent/divergent ( α < 0, α > 0) and stretching/shrinking channels. The combination of base fluid Silicon oil, and nanoparticles Mn–ZnFe 2 O 4 and CoFe 2 O 4 are suspended in casson hybrid nanofluid. The Mathematical problem is explored in the form of partial differential equations PDEs by considering Joule heating radiation, heat source and dissipation effects. The ordinary differential equations (ODEs) are obtained by employing the similarity transformations. The influence of various significant parameters on different distributions are displayed via numerical data. The physical quantities are calculated for the nanofluid, hybrid nanofluid and for α > 0 and α < 0 cases. The NDSolve approach is used to find the solution of the model. The key finding is that, the drag friction increases against porosity parameter and inertia parameter for nano and hybrid nanofluid. Furthermore, nusselt number increase in convergent channel and decrease in divergent channel for Eckert number EC and heat source Q . Additionally, it is concluded that hybrid nanofluid has more reactive performance than nanofluid.
