Numerical investigation of thermal improvement of system in existence of nanofluid and magnetic force

Abstract

The current article aims to simulate the promising influence of porous zones on treatment of working fluid within curved shaped containers under the impact of MHD. The MHD was applied in x direction which produces one negative source term in the y velocity equation. The features of base fluid have been improved with dispersing Al2O3 nanoparticles. The formulation based on Ψ was used to simplify the equations and finally the equations were solved via CVFEM. Results showed that dispersing nano-powders boost the convective rate about 39.34% in the presence of MHD. Increase in shape factor can make Nu increase about 11.46%. The applying MHD causes Nu to reduce about 54.93%. Augment of Ra makes Nu augments around 68.91%.
