| Popis: |
This paper presents two concurrent simulation strategies suited to compute the noise induced by external aerodynamic flows inside of vehicles. A typical applied problem would be the noise in a car induced by the flow around a side mirror. The traditional approach relies on a compressible, transient CFD computation. The result of such a computation contains both the vortical and acoustic pressure contributions: it can immediately be used in a standard vibroacoustic strategy to compute the noise inside of a vehicle. The second approach relies on an incompressible CFD strategy, complemented by an acoustic solver. The paper discusses some advantages of this second strategy and gives illustrations on an SAE body (simplified car concept). |
