Chemically reactive flow and heat transfer of magnetite Oldroyd-B nanofluid subject to stratifications

As an emerging technology owing to countless worthy properties, nanofluids have been concerned by numerous scientists and developed a very energetic arena. Nanofluids, a colloidal assortment of nanoparticles and widespread analysis have disclosed applications of heat transfer because of their intensified aspects of thermal conductivity. The present article explores the nanofluid characteristics on MHD flow of an Oldroyd-B liquid. The convective and stratification mechanisms in the manifestation of thermal radiation and chemical reaction have been utilized for heat and mass transfer features. Additionally, the phenomenon of heat sink/source is accounted. The mathematical relation is established by means of usual boundary layer estimates. Homotopic approach has been utilized for the computation of resultant non-linear ODEs. Thermophysical properties of numerous somatic parameters on velocity, temperature and concentration are scheduled in plots as well as in tabular form. The present interruption reports that the liquid temperature declines for thermal stratification parameter, although conflicting trend is being noted for radiation parameter and thermal Biot number on temperature of Oldroyd-B fluid. The mass Biot number and chemical reaction parameter displays diminishing tendency on concentration field. Additionally, for authentication of current derived elucidations an assessment table of skin friction coefficient is prepared in restrictive cases.
