Role of hybrid nanoparticles in thermal performance of Sutterby fluid, the ethylene glycol

This articles analyses the thermal performance of mixture of ethylene glycol and hybrid nanoparticles (MoS2 and SiO2). Three dimensional heat transfer in the mixture of ethylene glycol liquid (the Sutterby rheology) and hybrid nanoparticles is modeled and obtained highly complex mathematical models are solved by finite element method (FEM). Numerical experiments are carried out to compare thermal performances of working hybrid Sutterby nanofluid (mixture of Sutterby fluid, MoS2 and SiO2) and working Sutterby nanofluid (mixture of Sutterby fluid and SiO2). The effectiveness of thermal conductivity of hybrid nano-Sutterby fluid is more than the effectiveness of thermal conductivity of nanofluid. Therefore, the usage of hybrid nanofluid in thermal and cooling systems is recommended. As in this work, it is proven that the thermal performance of hybrid nanofluid is greater than the thermal performance of nanofluid. Therefore, hybrid nanoparticles are recommended to enhance thermal performance of working fluid. Surprisingly, the momentum boundary layer thickness in hybrid Sutterby liquid is greater than in conventional working fluid or nanofluid. Eventually, a significant reduction in thermal resistance of hybrid Sutterby nano-liquid is observed. Surface heat flux for the case of hybrid nanofluid is greater than that for the case of nanofluid or base fluid. (C) 2019 Elsevier B.V. All rights reserved.
