Thermal and solutal stratifications in flow of Oldroyd-B nanofluid with variable conductivity

This article reports the heat transfer enhancement on magnetohydrodynamic (MHD) flow of Oldroyd-B nanofluid influenced by stretching cylinder. The aspects of mixed convection and heat sink/source are considered. The model used for nanofluid incorporate the properties of Brownian motion and thermophoresis. The temperature-dependent thermal conductivity with the influence of thermal and mass stratifications is adopted. The nonlinear PDEs are condensed into ODEs via apposite conversions. The analytically homotopic approach has been adopted to elucidate the nonlinear ODEs. The stimulus of essential concerns on velocity, temperature, concentration, Nusselt number and Sherwood number is depicted. This analysis reported that the liquid velocity has a conflicting tendency for larger magnetic and mixed convection parameter. Furthermore, the liquid temperature decays for the higher thermal stratification parameter, whereas analogous influence is being noticed for mass stratification parameter on concentration field. For the confirmation of these outcomes an assessment table with former effort is also established.
