The study is done on a subsonic Fan stage and interaction noise between the fan wakes and the Outlet Guide Vanes (OGV) is considered. For this purpose, the Linearized Euler Equations (LEE) are solved with a steady axisymmetric flow. The acoustic sources are modelled by a scattering approach. Numerical simulations are carried out in an unwrapped cylindrical layer using a high-order finite volume solver. In order to explicitly take into account the moving fan blades into the propagation medium, a high-resolution sliding mesh technique is used. The simulation results, which highlight the screen effect of moving fan blades on fan/OGV interaction tones, are consistent with analytical literature.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/AeroacousticsTurbojet fan noiseOutlet guide vaneTurbomachinesLinearized Euler equationsScreen effectFanHigh order finite volumesjournal articleopen access10.1016/j.jsv.2020.115428
