A Comparison of the Measured and Predicted Flowfield in a Modern Fan-Bypass Configuration

A 3-D viscous Navier-Stokes flow solver was used to predict core and bypass rotor performance and radial flow characteristics of a 4.6:1 bypass ratio, single stage fan. The 3-D flow solver can handle several blade rows simultaneously and has the capability to include a downstream splitter. Results of the analysis are compared with experimental data obtained during rig testing of a modern high bypass single stage turbofan in which rotor performance for both bypass and core streams was measured.Copyright © 1992 by ASME
