Thermal performance of magnetohydrodynamic complex fluid using nano and hybrid nanoparticles

Abstract This work investigates the role of hybrid nanoparticles in the transportation of heat in ethylene glycol. Governing mathematical models with correlations for the effective thermal properties due to the inclusion of nanoparticles and hybrid nanoparticles are solved by the finite element method (FEM). This theoretical investigation has confirmed that the inclusion of hybrid nanoparticles leads to the highest heat transport as compared to the transport of heat caused by a nanofluid. Therefore, for efficient thermal systems, the inclusion of hybrid nanoparticles is recommended rather than the single kind of nanoparticles. This information about the efficiency of nanoparticles is obtained by performing numerical experiments using M o S 2 and Si O 2 as a (hybrid nanoparticles) and ethylene glycol as a base fluid. The rate of the heat transfer in hybrid nano-ethylene glycol is greater than the rate of heat transfer in nano-ethylene glycol. For maximum heat transfer in ethylene glycol, dispersion of M o S 2 and Si O 2 are recommended rather than M o S 2 . It is also observed that wall shear stress in case of flow of mixture ethylene glycol, M o S 2 and Si O 2 is less than the wall shear stress for the case of mixture of ethylene glycol and M o S 2 .
