Abstract

The influences of Al₂O₃ nanoparticles with various shapes on thermal characteristics of nanofluid within a permeable space concerning magnetic force have been simulated by means of CVFEM. To form the final PDEs, radiation term has been incorporated. Impacts of magnetic force, radiation constraint, Rayleigh number and shape factor on nanomaterial behaviour have been analysed. Results demonstrate that the higher values of shape factor lead to augmented convective heat transfer. By augmenting the magnetic strength, conductive heat transfer can be predominant than that of the convection.
