temperatures of oil and engine solids. A 3D model of natural convection & radiation in the engine bay was built
in STAR-CCM+ where the primary boundaries for heat transfer between the surrounding air in the underhood
region and engine solids were defined. The two models were run simultaneously and data were exchanged for
the surface temperatures of the primary engine components as well as the heat transfer rate between these
components and the engine bay surroundings.

Cycle (WLTC) with additional shut-down periods during which the car was assumed to be parked in a quiescent

present work can thus serve as a solid basis for implementing more advanced thermal management models in
the future.},
