Abstract: Turbochargers with high flow rates and high pressure ratios exhibit increased compression ratios and larger volumetric flow rates, resulting in a significant boost in the energy of compressed air discharged by the compressor, which generates exhaust noise characterized by high-frequency broadband features at the compressor outlet. To enhance both noise reduction effectiveness and airflow efficiency comprehensively, this paper introduces an innovative design of an inline corrugated perforated muffler. This muffler integrates the noise reduction principles of corrugated tubes and perforated plates, featuring a compact structure with small space occupation and a large flow cross-section. It is suitable for high-speed airflow pipes, with low airflow pressure loss and excellent noise reduction. The internal sound field of the muffler is analyzed using the finite element method combined with a two-dimensional axisymmetric structure-acoustic coupling model. An experimental setup is constructed based on the dual-load method to measure the acoustic performance of the corrugated tube. The analysis of the impact of corrugated tube structural parameters on the muffler's transmission loss reveals the order of primary and secondary factors as follows: perforation rate of the perforated plate、corrugation width、corrugation spacing、corrugation height.
