CFD study of electric motor's cooling

Nowadays electrification is one of the leading fields of engineering as it is seen as one of the key factors that can reduce environmental impact of human activities by reducing theirs polluting emissions. Mobility is the sector in which electric driven systems are diffusing the most. The search for performance in one of its main component, the electric motor, is therefore of fundamental importance in terms of efficiency and reliability of every electric driven applications. The optimization of thermal aspects covers a primary role and highly affect power consumption and lifetime of components. With this intent the use of CFD, Computational Fluid Dynamics, allows to exploit most of heat transfer aspects which concurs on thermal behavior both for design phase and performance estimations. The work of this thesis investigates the cooling performances of the motor driving an electric vehicle made by Engines Engineering -EE- which is a company that projects motorbikes for thirds and is recently going to expand in the field of electric mobility. Beside the specific case studied, the methods can be extended to any component which require a thermal management as CFD tools are fundamental in a very wide spectrum of application in engineering.
