Abstract
The axial compressor performance prediction method was developed
based on streamline curvature method
according to the flow mechanics of transonic axial compressor.This method considered the series impacts of deviation and loss to a certain extent according to the national and international openning research progresses.The internal flow field of NASA(National Aeronautics and Space Administration) TP1659 was calculated
thus obtained the span-wise aerodynamic parameters and characteristic curves at design and off-design points.With the comparison between simulation and experimental value
this method and models are validated to be applicable
and can be used for compressor design and optimization.
