Abstract

Abstract This article delves into the intricate relationship between the modeling parameters of an axial supersonic through-flow fan (STFF) rotor and its performance based on an active subspace method. It considers the influence of the STFF rotor key parameters on its performance. Implementing the active subspace method generates cloud maps to visualize the performance of the STFF rotor. Moreover, this study investigates the correlation between Bezier curve variables for constructing blade angles and critical performance metrics, such as the total pressure ratio and isentropic efficiency. After a 50 % chord length, the Bezier control point parameters dominate the effect on the total pressure ratio with a linear relationship. This article provides comparative flow field analyses on the blade elements with different performances under three working conditions. Under the constraint of the blade chamber turning angle, there is a linear relationship between the upper and lower limits of the isentropic efficiency distribution and total pressure ratio. This study shows that the total pressure ratio, installation angle, and maximum deflection value are positively associated. Further analysis provides an empirical formula.

超声速通流风机转子主动子空性能分析

摘要基于主动子空间方法研究了轴向超声速通流风机(STFF)转子建模参数与其性能之间的复杂关系。考虑了STFF转子关键参数对其性能的影响。实现有源子空间方法生成云图，以可视化转子的性能。此外，本文还研究了构建叶片角度的Bezier曲线变量与关键性能指标(如总压比和等熵效率)之间的相关性。在50 %弦长后，贝塞尔控制点参数对总压比的影响呈线性关系。本文对不同性能的叶片元件在三种工况下的流场进行了对比分析。在叶片腔室转角约束下，等熵效率分布的上下限与总压比呈线性关系。研究表明，总压比、安装角与最大挠度值呈正相关。进一步的分析提供了一个经验公式。
