  • With the help of software Fine/Design3Dand a computational fluid dynamics(CFD) method,the optimization design of a three-dimensional blade was carried out for fan/compressor.Then three-dimensional numerical simulation software named Fine/Turbo was used to calculate typical working conditions of both the new fan/compressor and the initial one at design rotating speed.The flow field performance under design speed condition was obtained.Numerical results show that efficiency is increased by 1.05% at design point after optimization of fan blade,without changing the stage total pressure ratio.The optimization obviously improves,especially in the fan stream,the flow structure and parameters of the fan/compressor's main flow.
