The Wave Fan was developed for the past 10 years. In the developing procedures, many leading edge technologies were adapted such as Aeroacoustic analogy prediction, surface pressure measurements, Computational Fluid Dynamics and Laser Doppler Velocitimeter. The Wave Fan is well known because of its unique design. Now the Wave Fan becomes a best in class automotive part in the world and becomes a name of the lower noise fan. But for the specific vehicle application, it needs some modification and optimizations for the best of the system performance. In this paper we can discuss the surface response method to meet customer requirement and to optimize system performance. The uneven blade spacing technique is also applied to minimize the unpleasant discrete tonal noise.
