Abstract: With the help of software Fine/ Design 3D and a computational fluid dynamics
(CFD) method, theoptimization 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. T he optimization
obviously improves, especially in the fan stream, the flow structure and parameters of the
fan/ compressor. s main flow.
