Entropy analysis of nanofluid magnetohydrodynamic convection flow past an inclined surface: A numerical review

Abstract

A numerical investigation is conducted to review the entropy study of magnetohydrodynamic (MHD) convection nanofluid flow from an inclined surface. In evaluating the thermophoresis and Brownian motion impacts, Buongiorno's model is applied to nanofluid transfer. Using Keller's implicit box technique, the governing partial differential conservation equations and wall and free stream boundary conditions are made into the dimensionless form and solved computationally. For different thermos physical parameter values, the numerical results are discussed both graphically and numerically. Verification of the present code with previous Newtonian responses is also included. To analyze the variability in fluid velocity, temperature, nanoparticle volume fraction, entropy, Bejan number, shear stress rate, wall heat, and mass transfer rates, graphical and tabulated results are reported. The study suggests applications in the manufacturing of nanomaterial fabrication, and so on.

Hall and ion‐slip effects on nanofluid transport from a vertical surface: Buongiorno's model

“…The nonlinearity of the emerging model does not permit exact solutions and therefore an implicit finite difference computational method (Keller's box scheme) [35] is utilized. The present Keller-Box results are validated with the earlier Newtonian studies [36][37][38][39][40] available in the literature. The study finds applications in heat exchangers technology, materials processing and geothermal energy storage etc.…”
