Abstract

The aeronautic industry has concentrated its efforts on researches and improvements in context of electrification aiming to solve problems like noise, gases emission and efficiency. There are many challenges to be tackled within an electrified aircraft but one that deserves special attention is battery system thermal management, due to the amount of energy storaged in the modules and safety requirements. In order to improve thermal management of batteries for aviation, this paper studies a heat exchanger, in this case a cold-plate, where different flow rates and tube diameters were simulated aiming to understand the influence of these changes in heat transfer. To this, it was used both analytical and numerical methods. The analytical method was developed using the open source simulation software Octave, where heat transfer equations were implemented and the numerical method was developed using Fluent-Ansys academic license. So far, the results obtained show that with an increase in flow rate the temperature variation decreases, and with an increase in the tube diameter the temperature variation also increases.
