Thesis work: Electric motor internal heat convection modeling and analysis
Goal
To estimate the heat convection coefficients between the internal surfaces of a permanently magnetized electric motor for an electric vehicle, using computational fluid dynamic (CFD) software.
Background
Electric motors in vehicles are exposed to largely varying load magnitudes for different time extents, during which it is very important not to overheat the motor. The internal temperatures are preferably predicted using lumped parameter thermal networks, in which all major conductive, convective and radiant heat transfer paths and rates are included. Due to the complex geometry inside the electric motor, as well as the dependency of rotational speed, estimation of the internal convective heat transfer rates demands fluid dynamics modelling and simulations. It would be valuable to investigate how the relevant internal convective heat transfer coefficients vary with operating speed and temperature for a permanently magnetized synchronous electric motor.
Plan
Study convective internal heat transfer in geometries of varying degree of complexity, and finally of an existing motor. Model and simulate internal air flow, and determine the heat transfer coefficients' dependence on rotating speed and temperature. Compare with previously published empirical models. Implement the suggested coefficients in a Lumped-parameter-model for analysis.
