Numerical study of a liquid-film with heat transfer: application to the cooling of electric engines
The context of the internship is the cooling of electric engines. The heat generated by the electric motor is due to losses within multiple components like stator windings and rotor magnets or conductors. Among the different cooling strategies, we focus this study on an active convective cooling technology, where heat is removed from the motor and transferred to another location to eventually be rejected to the ambient environment.
Heat may be extracted through active cooling such as a cooling jacket or a spray injecting directly a cold liquid on the stator or the rotor. To design and evaluate the performance of such a cooling system, we need to estimate the heat transfer coefficients between the solid part of the motor (stator windings, rotor magnets…) and the cooling liquid-film flowing over it.
The objective of the internship is to numerically study representative ca [...]
