The induction noise is a major noise source of gas turbines. The resistance loss and noise attenuation of the intake air filter and the intake silencer of a gas turbine were analyzed by using the Computational Fluid Dynamics (CFD) method and the Acoustical Finite Element Method (Acoustical FEM). Influence of different parameters of the filter structure on the performance of the air intake system and the silencer was studied. This work may provide a guidance for optimal de-sign for the air intake systems of gas turbines.
