【 摘 要 】

This contemporary study is done to analyze the comparative study of hybrid nanofluids motion due to semi-infinite asymmetric channel with contracting and expanding porous walls orthogonally. Boundary conditions considered are convective conditions. Hybrid nanofluids consist of more than two nanoparticles. Purpose of nanofluid is to enhance the heat transfer characteristics by adding nanoparticles into base fluid. When we add two nanoparticles collectively to form nanofluid than it is more useful. Maganese Zinc ferrite and Nickle Zinc ferrite are used as nanoparticles and engine oil and Kerosene oil are considered in place of base fluid. Nonlinear heat source sink effect is considered along with activation energy. Darcy Forchheimer porous medium is considered in momentum equation. We have introduces suitable transformations to get ODE’s from PDE’s. Homotopy analysis method is used to find the convergent solution. For more accuracy tables are also drawn for convergent solution. Velocity for MnZnFe2O4-NiZnFe2O4-C10H22-C8H18 is lowest among all. Impact of important parameters along velocity, temperature, concentration, skin friction and Nusselt number is seen through graphs. For positive values of wall contraction (or expansion) rate parameter velocity of the fluid enhances. Motion slows down for greater Forchheimer number. Temperature rises via thermal Biot number. Concentration profile is increasing with larger estimation of activation energy.
