- Silencers are an essential component of noise reduction systems. Traditional compressible flow simulations struggle to solve the very low Mach number flows in these devices. In contrast, our model is robust, does not suffer from being computationally stiff and provides reliable converging simulations. The work described in this paper led directly to a subsequent project, funded by Jaguar-Landrover, (Steven Pierson, spierso2@jaguarlandrover.com), to predict high frequency noise from automotive silencers.
