NVH (noise, vibration and harshness) is an overall measure of the ``feel'' of a vehicle reflecting the noise level, vibration, and harshness felt while driving. NVH has become an important part of an automotive quality indicator with the customer's perception of quality being based, in part, on sound levels in the passenger compartment. With the introduction of weight-saving under-hood components, and emphasis on passenger compartment noise levels, the problem of flow-generated noise, both interior and exterior, has become an important issue for the automotive industry. Although aeroacoustic simulation has the promise to provide tools for estimating flow-generated noise, it is also very challenging because it can require the simulation of time-dependent turbulent fluid dynamics, structural dynamics and the associated acoustic sources. Of course, the simulated aeroacoustic fields must contain an appropriate frequency spectrum in order to be relevant for automotive design making reliable predictions of ``noise'' computationally demanding as well.
The focus of this special session is on the simulation-for-design issues associated with flow-generated noise, i.e., aeroacoustics for the automotive industry. The goal for the session is to highlight current problems in aeroacoustics for automotive design and expose possible solutions. The organizers encourage contributions from automotive designers, analysts, and researchers. Contributions that focus on the application of commercial codes for automotive aeroacoustic design are also highly encouraged.
