Abstract: A new loss and deviation model suitable for multi-stage transonic axial compressor was developed according to the research findings publicly available.Along with 3-D modification,numerical simulation was performed for two-stage transonic axial compressor using an improved streamline curvature method,thus obtaining the characteristic curve of design point and off-design point.By combining the calculated results with experimental value,this model and method are suitable for engineering calculation with higher accuracy of design point and off-design point.
