Numerical Study of MHD Natural Convection in Partially Heated Cubical Cavity Filled with Hybrid Nanofluid

Article Preview

Abstract:

In this study, natural convection of a hybrid nanofluid inside a cubic cavity under the influence of a constant external magnetic field is numerically investigated by using control volume method. The cavity is partially heated from the left wall with uniform temperature and cooled from the opposite wall while the other sides are kept adiabatic. Analysis is focused on the impact of some parameters, including Hartmann number (0≤Ha≤100), Rayleigh number (103≤Ra≤106), nanoparticle volume fraction (0≤Φs≤0.06) and heater band width (1/3≤ ɛ ≤1). The Analysis of the results related to the dynamic and thermal structures, as well as the average Nusselt number, revealed that the effect of the external magnetic field exerts a negative influence on heat transfer within the cavity. However, more favorable findings were observed when the volume fraction of nanoparticles was increased, as well as when the width of the heater band was increased.
