| Abstract: | The induction noise is a major noise source of gas turbine. The resistance loss and noise attenuation of the intake air filter and intake silencer were analyzed by using the Computational Fluid Dynamics (CFD) method and the Acoustical Finite Element Method (Acoustical FEM). Different parameters of the filter structure were studied. Also the performance of the air intake system and the silencer were studied in order to improve the design of the air intake silencer. |
