To predict fan noise level, the hybrid scheme, i.e., the combinational approach of a numerical simulation based on the three-dimensional unsteady Reynolds-averaged Navier-Stokes (URANS) equations and an analytical calculation based on the three-dimensional linear singularity theory, is to be improved. It takes into account the acoustic effects on the unsteady loading on the rotor blades as well as the stator vanes. The calculated noise level is compared more favorably with the experimental data, and the superiority of the improved hybrid scheme is confirmed.
