Effects of Brownian Motion and Thermophoresis on the Mixed Convection of Nanofluid in a Porous Channel Including Flow Reversal

摘要: This article is devoted to combined convection heat transfer of nanofluids through a vertical channel filled with homogeneous and isotropic porous medium. The flow assumed be fully developed the “Brinkman extended Darcy” model used for in media “clear compatible” viscous dissipation considered. Also utilized nanofluid incorporates effects Brownian motion thermophoresis. governing momentum, energy, nanopartices volume fraction equations are solved both analytically numerically. influential dimensionless parameters such as thermophoresis parameters, mixed parameter (Gr/Re), Brinkman, Darcy Lewis numbers on velocity temperature distributions pressure drop studied. Also, results Nusselt number left right walls presented discussed.
