In order to reduce rotor-stator interaction noise on future high-bypass engines, silent OGVs have to be designed. This study will focus on noise predictions by means of weakly compressible and compressible lattice Boltzmann simulations, along with aerodynamic assessment. Computations will be performed on a full test rig including a grid generated turbulence interacting with a 7-vanes cascade.
