【 摘 要 】

Aerodynamic noise is the main noise source produced by industrial gas turbines. It brings harm to production and life. Muffler is the key component to suppress aerodynamic noise. In this paper, the influence of the structure parameters such as the diversion angle, films number and porosity of the absorber for the noise reduction effect is studied, which provides the basis for the structure design and optimization of the muffler.
