Abstract

Abstract: In order to explore the mechanism of non-axisymmetric endwall reducing flow losses， a method in accordance with hub static pressure was proposed， which was based on the principle of non-axisymmetric endwall profiling. This paper takes Rotor37 as the research object， NUMECA/Auto-Blade， Design3d and EURANUS flow solver were carried out to make the endwall， optimization and numerical calculation respectively. The effects of the overall performance of compressor rotor with profiled endwall were analyzed. Results indicate that the non-axisymmetric endwall based on hub static pressure can effectively reduce the transverse pressure gradient of the blade passage， inhibit the premature separation appearing on the suction surface. In addition， the distribution of blade surface pressure becomes more uniform， and the blade exit total pressure loss coefficient is reduced by 8.94%. Thus， the profiling method based on hub static pressure was proved to be effective.

Key words: Non-axisymmetric endwall；Compressor rotor；Hub static pressure；Endwall profiling

摘要： 为探究非轴对称端壁减小流动损失的机理，根据非轴对称端壁造型基本原理，提出了一种基于轮毂静压构造非轴对称端壁的方法。以Rotor37为研究对象，采用NUMECA/Auto- Blade和Design3d进行端壁造型和优化，并使用EURANUS流场求解器进行数值计算，分析了造型后端壁对压气机转子总体性能的影响。结果表明:基于轮毂静压的非轴对称端壁能有效减小叶片通道的横向压差，抑制气流在吸力面出现过早分离，且叶片表面的压力分布更加均匀，叶片出口总压损失系数降低了8.94%，证实了基于轮毂静压构造非轴对称端壁方法的有效性。
