Transportation of radiative energy in viscoelastic nanofluid considering buoyancy forces and convective conditions

摘要

These days, the most important requirement of contemporary technological activities is extraordinary performance chilling for standard construction. Weaker thermal transference is meaningful issue to keep the extraordinary performance chilling throughout manufacturing systems. This difficulty can be determined by the nanoparticles submersion. Thus, a rheological model featuring thermophoretic and Brownian diffusions is introduced to formulate the two-dimensional viscoelastic (second-grade) nanoliquid flow considering mixed convection and magnetohydrodynamics. Modeling subject to viscous dissipation, convective conditions, Joule heating, heat absorption/generation, stratifications and radiation aspects is presented. Non-dimensionalization process is performed introducing apposite variables. Homotopy algorithm is opted for nonlinear analysis. Graphs are exhibited for interpretation of distinct variables influence against dimensionless quantities. We found opposing behavior for radiation and thermal stratification variables against thermal field. (C) 2019 Elsevier Ltd. All rights reserved.
