Numerical simulation for forced convection flow of MHD CuO-H2O nanofluid inside a cavity by means of LBM

Abstract

This article employs mesoscopic approach to investigate CuO-H2O nanofluid inside a cavity with hot obstacle. Influence of magnetic field is retained. Lattice Boltzmann method (LBM) is selected as simulation tool. Brownian motion impact is added in model of nanofluid. Roles of Reynolds number (Re), CuO-H2O nanofluid volume fraction (ϕ), Darcy number (Da) and Hartmann number (Ha) are demonstrated. Results reveal that thermal plume diminishes with augment of (Ha). Convective mode improves with the increase of Da and Re. It is observed that temperature gradient is an increasing function of Hartmann number.
