Abstract

A computational analysis of the thermal management system of a battery-pack, whereby the cells are actively cooled at their surfaces by being immersed in a nanofluid medium. Nanofluids used in the automotive and energy management systems are selected and modelled within this work. The present study is conducted by carefully observing the flow structures, thermal energy distribution, entropy generation and pumping power requirements within the battery-pack, to be able to present a resource helpful for designers in the preliminary stages of their thermal management system. This study throws light beyond the case of the battery-pack thermal management, to other applications that require to be maintained at a given temperature or require a certain quantity of heat to be removed from it.
