Fan noise prediction method using unsteady CFD analysis has been developed. It is a hybrid scheme of CFD and linear theory, in which fan noise sources are predicted by unsteady 3D CFD analysis and acoustic power levels in a fan duct are predicted by 3D linear theory. Distributions of fan noise sources predicted by 3D CFD analysis are compared with 2D and 3D linear theory. Acoustic power levels calculated from noise sources of 3D CFD and 3D linear theory are compared and evaluated using fan noise test results.
