Abstract

In this manuscript, to simultaneously inhibit multiple causes of corner separation and therefore improve the flow around endwall as much as possible, the combined control by both Full Blended Blade and Endwall (Full-BBEW) and endwall Vortex Generator (VG) are studied. Firstly, a Full-BBEW design is built for a linear cascade and then an combined control is carefully designed by placing a VG in the middle passage of Full-BBEW design. Both numerical and experimental analyses over the entire working condition are performed. Results demonstrate that the combined design significantly reduces overall aerodynamic losses across the full range of design Mach number, with a more pronounced effect observed at high incidence angles. The combined BBEW and VG design provides a comprehensive control strategy that mitigates corner separation and improves endwall flow, resulting in improved aerodynamic performance.

压气机转角分离组合设计的实验与数值研究

为了同时抑制多种原因导致的角分离，从而尽可能地改善端壁周围的流动，本文研究了叶片与端壁完全混合（Full- bbew）和端壁涡发生器（VG）的联合控制。首先，建立了线性级联的Full-BBEW设计，然后通过在Full-BBEW设计的中间通道放置VG来精心设计组合控制。对整个工况进行了数值和实验分析。结果表明，在整个设计马赫数范围内，组合设计显著降低了整体气动损失，在大入射角时效果更为明显。BBEW和VG的组合设计提供了一种全面的控制策略，可以减轻转角分离，改善端壁流动，从而改善气动性能。
