Coupled multiphysical modeling of electric motor thermal management (electromagnetic-thermofluidic)
Advanced automotive e-drive systems are being thermally-throttled, however the ability to analyze the complex impact on temperature within these systems are sill not well understood.
This study is focused on applying CFD, FEM techniques to fully resolve the complex interaction across multiphysical aspects of automotive energy systems including electric motors, inverters, and batteries. By linking FVM (OpenFOAM) and FEM (Elmer FEM), a feedback loop is formed as above. Based on this study, it is meaningful to implement it closer to the actual physical phenomenon by conducting an electromagnetic field analysis on the resistance of the winding and the magnetic flux density of the permanent magnet based on temperature. These components are extremely temperature-sensitive, and a better understanding of their physics is required to push the envelop for a more efficient and durable e-mobility solutions.
