Résumé

ĂIn the coming years, more hybrid and full electric vehicles will be coming to the market and some new challenges will arise for noise and vibration engineers. One of them is the flow-induced noise within ducts and vents in HVAC systems leading potentially to customer complaints. Among the different strategies aimed at predicting the generation of noise by turbulent flows, hybrid approaches allow us to compute the acoustic pressure by assuming the decoupling of sound generation and propagation. In this work, different sound source formulations using either the pressure or the velocity field provided by an incompressible fluid dynamics simulation are investigated using Finite and Boundary Elements Methods. The different approaches are compared in the specific case consisting of a low Mach number flow in a rectangular duct obstructed by a diaphragm.
