These modules aim at cooling down the engine in combustion cars and the electrical components in EVs. During the fast charging process of such vehicles, a huge amount of power is transferred to the battery in a short period of time that causes its overheating. Several fans are installed in order to cool down these components, thus multiplying the noise sources that are propagated both outside and inside the cabin and can be harmful to the pedestrians as well as to the passengers. Lattice-Boltzmann simulations are performed on both the classical and the electrical module in order to understand the noise mechanisms and highlight the differences between them. Some additional work has been done on the classical module in terms of numerical modelling in order to better represent the experimental setup. The heat exchanger core tubes have been added to the setup and their aeroacoustic effect is being studied in the present study. Effect of the fan tip gap is also assessed. The results are compared with the experimental measurements achieved in the anechoic wind tunnel at Universite de Sherbrooke. Medium grid simulations are retained for the analysis as found in the previous study. 收起
