In this study, a parametric experimental investigation was conducted to explore the optimal steady endwall hole blowing configurations for managing corner separation in compressor cascades. Parameters such as injection location, momentum, and skew angle were investigated. A self-developed oil-flow visualization technique employed elucidate flow control mechanisms of blowing, while five-hole probe traverse used reveal impact on loss characteristics. The results indicate that streamwise...
In modern aircraft engines, precise control of the clearance between blades and casing or hub is essential to preventing contact during high-speed rotation. The penny structure compressor variable stator vanes (VSV) inevitably generates local radial blade, which deteriorates flow field adversely affects aerodynamic performance VSV. Moreover, different settings significantly influence this performance. This study experimentally investigates high-pressure VSV, employing steady-state hole-type...
The presence of bleed in an aero engine’s compressor can significantly impact its flow characteristics and contribute to rotating instability. This study focuses on the a typical cavity structure internal compressor, specifically circumferential non-uniformity aerodynamic stability. A numerical simulation involving multiple passages was conducted transonic high-pressure rotor E 3 considering structure. delves deep into non-uniform mechanisms behind their generation field. Furthermore,...
Variable geometry turbines are essential for adjusting operational conditions in industrial gas and variable cycle engines. These adjustments necessitate partial gaps at both ends of the guide vanes to alter turning angle, consequently introducing an aerodynamic performance penalty. Moreover, pivot layout profoundly influences losses. Research on turbine cascades that considers various gap layouts is limited, particularly terms experimental studies, which rarely conducted. This study aims...
Hyperbolic thin-shell cooling towers have complicated vibration modes, and are very sensitive to the effects of group wind-induced vibrations. Traditional aero-elastic models usually designed based on method stiffness simulation by continuous medium thin shell materials. However, has some shortages in actual engineering applications, so so-called "equivalent beam-net design method" is proposed paper an model with a proportion 1: 200 above integrated pressure measurements been carried out...
