跨声速轴流压气机非设计点特性计算

摘要

A loss and deviation angle model for transonic axial-flow compressor is developed based on the open literature.rnNumerical simulation of a certain type of transonic axial-flow compressor is carried out using streamline curvature method,rnthus obtaining the span-wise aerodynamic parameters and characteristic curves at design and off-design points. Therncomparison with test results indicates that the loss and deviation angle model is effective for the compressor performancernprediction.%基于公开发表的研究成果,发展了一种适用于跨声速轴流压气机的损失和落后角模型,采用流线曲率法对某单级跨声速轴流压气机进行了数值模拟,得到了展向参数分布和全工况下的性能曲线.通过与实验值的比较,验证了该方法和模型在跨声速轴流压气机非设计点性能预测中的有效性.
