Nanomaterial heat transfer within thermal porous system in presence of Lorentz force

A curved enclosure in attendance of MHD was evaluated in this article. Both outer cold and inner hot surfaces have curved shapes which boosts the convective rate. The impact of MHD in equations has been applied and there is one negative term is x direction if horizontal magnetic fields have been applied. Presence of such a field leads to generation of Lorentz force which prevents the nanofluid from moving faster. Such reduction in velocity with growth of Ha makes Nu decrease. Adding nanoparticles with greater m and & phi; can increase the convective flow. When Ra = 700, dispersing nano-powders can enhance the Nu in existence of MHD about 41.9%. When Ra = 150, Nu can improve about 12.01% if m is enhanced. Nu decreases around 40.1% with growth of Ha while it increases about 43.36% in existence of greater Ra.

Automated summary

This article evaluates a curved enclosure with MHD (magnetohydrodynamics). Both the outer cold surface and the inner hot surface have curved shapes, which enhance the convective rate. The equations of MHD have been applied, and a negative term is present in the x direction with the application of horizontal magnetic fields. The presence of such a field results in the generation of Lorentz force, which hinders the acceleration of the nanofluid. The addition of nanoparticles with higher m and φ values can increase the convective flow. When Ra = 700, dispersing nano-powders can enhance the Nu by about 41.9% in the presence of MHD. When Ra = 150, Nu can improve by about 12.01% with an increase in m. Nu decreases by around 40.1% with the growth of Ha, while it increases by approximately 43.36% in the presence of higher Ra.
