摘要

The unsteady magnetohydrodynamics (MHD) flow and radiative thermal transfer of viscous and Casson hybrid nanofluid through two surfaces in a permeable medium with chemical reaction are studied. The hybrid nanoparticles of alumina $\left({Al}_{2}{O}_{3}\right)$ $({Al}_{2}, O_{3})$ and copper ( $Cu$ $Cu$ ) are dispersed in the base fluids of water and sodium alginate $({C}_{6}{H}_{9}Na{O}_{7})$ $(C_{6} H_{9} N a O_{7})$ . The discretize equations are solved by implementing similarity variables and Keller-box methods. The comparison of the current results with the published results for validation is discovered in proper agreement. The impacts of squeeze, magnetic, porous media, chemical reaction, nanoparticles volume fraction and thermal radiation on behavior and physical quantities of flow are discussed. The graphical results show the wall shear stress, convective thermal and mass transfer of Casson hybrid nanofluid is greater than viscous hybrid nanofluid. The squeeze of two surfaces accelerates the fluid velocity, while it slows down in the middle of channel when $Ha$ $Ha$ , $Da$ $Da$ , and ${\phi }_{2}$ $ϕ_{2}$ increases. The reduction of convective thermal transfer and temperature discovers when ${R}_{d}$ $R_{d}$ and ${\phi }_{2}$ $ϕ_{2}$ escalates. The concentration enhance and rate of mass transfer reduce with the constructive chemical reaction, whereas contrary effects is shown for destructive chemical reaction.
