摘要：
Two dimensional combined free-forced convection of Cu-water nanofluid in a square enclosure filled with fluid saturated porous medium subjected to uniform magnetic field has been numerically analyzed in the present work. The mathematical formulation consists of Darcy–Brinkman Forchheimer extended momentum equation with the enclosure having adiabatic top and bottom walls and isothermally cooled vertical side walls. Study has been performed over various ranges of governing parameters like Richardson number, Darcy number, Hartmann number and solid volume fraction. The results are presented in the form of hydrodynamic and temperature fields, average Nusselt number, velocity graphs and they are discussed to expound the effects of the physical parameters in the solution. © 2017, Springer India Pvt.
