单级轴流风机准三维设计

详细地讨论了用流线曲率法对单级轴流风机进行准三维设计的方法和步骤,结合平面叶栅法和流线曲率法解决了单级轴流风机的设计问题,这种方法让叶片造型更加适应流场的分布,可以达到较好的增压效果.最后得到叶片前后缘气流参数和动静叶片中心面的形状,并对算例设计结果的压缩性能进行了评估.

Quasi-three-dimensional Design of Single-stage Axial-flow Compressor

This paper detailedly introduces the method and steps of quasi-three-dimensional design for single-stage axial-flow compressor with the method of stramline curvature.The design problem in single-stage axial-flow compressor has been solved by combining plane cascade design with method of streamline curvature.This method makes the blade profile more adapt the flow distribution and can achieve better pressurized effect.Finally the gas flow parameters and the shape of center plane of dynamic static blade are obtained,and the example is evaluated about its compression properties.
