| Abstract: | The deviation and loss models were developed by taking into account different influential factors using two-dimensional streamline curvature mathematic method at off-design conditions.The internal flow field of NASA(National Aeronautics and Space Administration) Stage 37 was calculated,and then the characteristic curves of design and off-design points were obtained.Through comparison between simulation and experimental values,the results show that the predicted characteristics and parameters distribution of... |
