SAE 2015 Noise and Vibration Conference and Exhibition

Technical Session Schedule

Wednesday, June 24

Intake / Exhaust (Part 1 of 3)
(Session Code: NVC101)

Room TBD  2:30 p.m.

This session covers experimental, computational, and analytical efforts related to the basic mechanisms and control techniques of noise and vibration in the breathing system (induction, combustion chamber, and exhaust) of naturally aspirated and supercharged/turbocharged engines. Noise sources include airborne, flow, flow‐acoustic and flow‐structure coupling.

Organizers - Raymond A. Kach, Ford Motor Co.; Philip Keller, BorgWarner Inc.; Ahmet Selamet, Ohio State University; Christopher Shaw, Visteon Climate Control
