Radiative flow of magnetic nanofluids over a moving surface with convective boundary condition

Abstract

The influence of convective boundary conditions and heat radiation on magnetic nanofluids (MNFs) flowing through a permeable moving plate is investigated numerically in this study. The governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) using suitable similarity variables. The ODEs are solved by implementing the built-in solver in Matlab called bvp4c. The stability analysis has supported our initial presumption that only the first solution is stable. The thermal performance between cobalt ferrite nanofluid and manganese-zinc ferrite nanofluid is compared, and it appears that cobalt ferrite nanofluid has a slightly better performance in heat transportation compared to manganese-zinc ferrite nanofluid. We also considered a higher amount of thermal radiation and Biot number to scrutinize the heat transfer performance of MNF, and we found out that a greater amount of these parameters are effective in improving the heat transfer rate.
