流线曲率 meaning in English

streamline curvature

The multi - stage axial compressor performance was measured using a streamline curvature method based on two - dimension ( axisymmetric ) mathematical model
摘要采用二维（轴对称）数学模型，应用流线曲率法求解多级轴流压气机特性。
The main object of this paper is to design a diagonal impeller , which requires small size and high rotating speed . the first step of the design is to solve the radial equilibrium equations on the s2 stream surface . second , the blades designed according to the results of the first step
方案计算是为二维设计做基础；二维设计是在s2流面内用流线曲率法求解完全径向平衡方程，利用流场计算的结果来初步判断设计的工程合理性；叶片造型利用s2流场的计算结果，近似沿着气流流面进行造型。
