This research aims to study the acoustic noise prediction and control of turbofan engine fan. In this paper, a thin-body BEM/FW-H method is developed to efficiently predict the propagation of fan sound wave in the duct. It is a hybrid method combining computational aeroacoustics with Boundary Element Method (BEM). And two main geometry parameters are modified to investigate the noise reduction of turbofan engine fan by using the numerical prediction method. The acoustic performance of differentdoi:10.23977/ieps.2017.1029 fatcat:ifbqsut2srhi5bkqs7pfvdthoq
