Design of a Perforated Muffler for a Regenerative Blower Used in Fuel Cell Application

Hyun Gwon Kil, Kwang Yeong Kim, Chan Lee

Abstract

A perforated muffler has been designed to reduce a high noise level that is generated from a regenerative blower used in fuel cell applications. The noise consists of two components such as discrete high frequency noise component at blade passing frequency (BPF) due to rotating impellers and broadband noise component due to turbulence in inflow and exhaust jet mixing. Main contribution into the high noise level is due to the discrete frequency noise component at high frequency 5800 Hz. In order to effectively reduce the noise level of regenerative blowers, a perforated muffler has been modelled in this paper. In order to identify important design factors, the design parametric study has been performed using transfer matrix method and finite element method (FEM). It has been implemented to design the perforated muffler that effectively reduces the high noise level of the regenerative blower.
