Abstract


In modern high bypass turbofan engines, the fan is a considerable component to the performance and efficiency of the entire engine. Fan efficiency directly affects specific fuel consumption of the engine. In the paper, the three dimensional (3-D) flow field through the transonic axial flow fan and the intake of the CF6-50 high bypass ratio turbofan engine is investigated at the takeoff hot day conditions. The fan under study has a large diameter, about 2.18 m. The fan has a number of 38 blades. Each blade is tapered, highly twisted, and has a long span. The real dimensions of both the fan and its intake are used in the current simulation. Furthermore, steady, compressible, turbulent, and viscous flow in both the intake and fan is solved. The computational domain is a periodic sector through both the fan and the intake zones.  Results obtained from the simulation show shock waves formed in the passage at the trailing edge of the suction side and propagate towards the opposite blade pressure side.
