Abstract
Mesoscopic method is employed to simulate MHD nanofluid flow inside a permeable cavity with hot elliptic obstacle. Simulation is carried by Lattice Boltzmann method (LBM). Brownian motion impact is accounted in model of nanofluid. Roles of Reynolds number Re, nanofluid volume fraction phi, Darcy number Da and Hartmann number Ha are demonstrated. Results reveal that thermal plume diminishes with augment of Ha. Convective mode improves by enhancement of Da and Re. (C) 2017 Elsevier Ltd. All rights reserved.
