Abstract:
We aim to investigate the noise generation mechanism in a generic geometry representing a typical air outlet of an HVAC system of a car. We use an Aero-Acoustic simulation based on Large-Eddy Simulation and an experiment to study the interaction between a throttle plate (used to control the flow rate) and fins (used to guide the flow). We can identify several sound generation mechanisms, of which the so-called Parker β-mode is the most prominent in the sensible frequency range. Our focus is on t...     »
