Abstract

In current attempt, a numerical code was developed to model the nanofluid free convected magnetized flow by porous cavity. Non-Darcy formula is carried out to include the term of porosity in momentum expression. Radiative phenomenon is reported for distinct nanoparticle shapes. Aspects of radiative constraint, shape factor, Rayleigh number, magnetic force, and nanoparticles’ shape on nanofluid magneto-hydrodynamic natural convection are analyzed. Result demonstrated that application of external magnetic force deteriorates the convection and this reduction is more perceptible at the greater permeability. The conductive heat transport is the dominating form of heat transportation under the impact of higher magnetic force. For the constant values of Rayleigh, Hartmann’s and Darcy number, Nu _avg is independent of shape factor and observes a direct association with the radiation parameter.
