SAE 2015 Noise and Vibration Conference and Exhibition

Technical Session Schedule

Monday, June 22

Wind Noise and Aeroacoustics
(Session Code: NVC208)

Room TBD  

This session is to present numerical and experimental work pertaining to noise due to flow around the vehicle body, such as flow-induced interior noise, flow over protrusions, sunroofs, windows, noise from ventilation systems, or flow noise in exhaust system. Papers on aerodynamics alone without sound are excluded. Numerical studies may include new models or models based on existing theory as long as they are adequately supported by experimental or theoretical verifications.
