In this paper, properties of flow and heat transfer of nanofluid in the spiral channel used in the cooling system of an electric motor are numerically investigated. The finite element method is used to solve the governing equations. The flow regime is considered as laminar and the base fluid is water. In addition to pure water flow, the effect of adding Aluminium-Oxide nanoparticles in the base fluid on the heat transfer performance of the cooling system is studied. The Reynolds number of the fluid, turns number of the spiral channel, volume fraction of the nanofluid, and pressure drop of the coolant are the most important evaluation parameters of this study.

Abstract

In this paper, properties of flow and heat transfer of nanofluid in the spiral channel used in the cooling system of an electric motor are numerically investigated. The finite element method is used to solve the governing equations. The flow regime is considered as laminar and the base fluid is water. In addition to pure water flow, the effect of adding Aluminium-Oxide nanoparticles in the base fluid on the heat transfer performance of the cooling system is studied. The Reynolds number of the fluid, turns number of the spiral channel, volume fraction of the nanofluid, and pressure drop of the coolant are the most important evaluation parameters of this study. Heat transfer analyses are performed based on computational fluid dynamics and 3D fluid motion analysis.
