Abstract

This study reports the flow, thermal and concentration attributes of magnetic-nanofluids past an elongated plate with thermal radiation and chemical reaction. The flow considered is two-dimensional and time-dependent. The pressure gradient and ohmic heating terms are neglected in this analysis. The flow governing PDEs are transformed into ODEs using appropriate conversions. Further, the set of ODEs are solved analytically using perturbation technique. The flow quantities such as velocity, thermal and concentration fields are discussed under the influence of various pertinent parameters namely volume fraction of nanoparticle, magnetic field, stretching parameter, Soret number, radiation and chemical reaction with the assistance of graphical representations. Moreover, wall friction, reduce Nusselt and Sherwood numbers are calculated and deployed in tabular forms. Dual nature is observed for water-based Fe3O4 nanofluid and Ethylene glycol based Fe3O4 nanofluid. The results indicate that water-based ferrofluids are highly influenced as compared with Ethylene Glycol based ferrofluids. Also, the nanoparticle volume fraction plays a vital role in controlling the wall friction and heat transfer performance. Also, Soret parameter has a tendency to integrate high density particles in a boundary to raise the thickness of a surface.
