Enhancement of MHD radiative CNT-50% water + 50% ethylene glycol nanoliquid performance in cooling an electronic heat sink featuring wavy fins

Abstract

The aim of this research is to investigate numerically the efficiency of employing Carbon Nanotube (CNT)−50 Water + 50 Ethylene Glycol nanofluid into an inclined box heat dissipator featured with wavy fins beneath the impact of Lorentz forces, taking into consideration the nanoliquid radiative effect. The study is established using the Comsol Multiphysics software. The effects of Rayleigh number , Hartmann number , the radiative emitting coefficient , the fins waves number , the heat dissipator box inclination and the wavy fins dispositions are all analyzed as parameters that affect the heat sink proficiency. A comparison between flat and wavy fins is established. The data reveals that increasing Rayleigh number supports the convection cooling efficiency, by contrast, the presence of Lorentz forces reduces it. In addition, expanding the radiative coefficient enhances the heat sink proficiency. Whenever the radiation phenomenon is maintained, the influence of Lorentz forces is reduced. Furthermore, employing wavy fins provides the heat convection proficiency more better than flat fins and the excellent heat cooling proficiency is gained with fins waves number of λ = 2.
