Three dimensional MHD natural convection nanofluids flow with heat and mass flux from vertical surface in porous medium

Abstract

In This paper we investigate the MHD natural convective boundary layer flow of electrically-conducting nanofluids from a stationary vertical porous surface in a permable porous medium. The mathematical model is formulated by considering water-based nanofluids containing metallic Nano-particles for stationary plate cases. Three nanofluids are examined, namely copper, aluminum oxide or titanium oxide in water. Validation of finite element solutions for skin friction and Nusselt number is achieved via comparison with the previously published work, Primary and secondary velocities are consistently elevated with increasing Soret, thermal Grashof and solutal Grashof numbers. Increasing Schmidt number, chemical reaction and suction parameter both suppress Nano-particle concentration whereas the converse behavior is computed with increasing Soret number.
