Abstract
Nanofluids are stable colloidal suspensions of metal or nonmetal element in a disreputable liquid, which intensify the heat transfer of the solution and exaggerate the storage aptitude. The forthright intention of this communication is to scrutinize the impact of binary chemical reaction and activation energy on dual nature structure for unsteady flow of Carreau magnetite nanofluid owing to shrinking/stretching sheet. In addition, the collective stimulus of convective conditions with nonlinear thermal radiation, viscous dissipation, joule heating and heat sink/source has been established for heat and mass transport phenomena. With assistance of compatible conversions, the partial differential equations are condensed into ordinary differential equations which are then elucidated numerically via bvp4c scheme and the impacts of intricate parameters on the flow fields are exposed explicitly. It is noted that the intensifying values of activation energy parameter and fitted rate constant clue to an enhancement in the nanofluid concentration.
