摘要

针对带肋双层壁在曲面部件应用时，偏转内流与非均匀出流交互作用机理和传热冷却特性不明晰的问题，采用共轭传热方法对比分析了凸面、平面和凹面带肋双层壁在5种吹风比下狭窄内腔流动、非均匀出流和综合冷却特性。将平面带肋计算结果与实验结果进行对比，验证数值计算的准确性。通过横向平均综合冷效等参数，分析不同结构及吹风比下的气膜冷却和冲击冷却性能。通过无量纲速度、温度和流线，分析气膜、冲击冷却与偏转内流的耦合关系以及双层壁流阻特性。数值结果表明：降低冷气量要求下，冷效较高的吹风比为0.6；在冲击腔室内，肋柱近冲击驻点一侧冷效较高，近气膜孔侧流动分离导致冷效较低，带肋双层壁流速比无肋结构快且流线更具规律性；凸面双层壁气膜孔出流冷气在外壁贴壁效果最佳，凹面双层壁气膜孔出流冷气脱离壁面进入主流较多；吹风比为0.6时，凸面双层壁面平均综合冷效比凹面提高了约8.09%。该研究可为透平叶片曲面带肋双层壁结构的冷却设计和性能分析提供理论依据。

Abstract

To make clear the interaction mechanism between deflected internal flow and non-uniform outflow

as well as the heat transfer and cooling characteristics of pin-fin double-wall structures in curved components

a conjugate heat transfer method is employed to comparatively analyze the narrow-channel internal flow

non-uniform coolant outflow

and overall cooling performance of convex

flat

and concave pin-fin double-wall configurations at five different blowing ratios. Numerical results for the flat pin-fin structure are validated against experimental data to ensure the accuracy of simulations. The film and impingement cooling performance for different structures at different blowing ratios are analyzed based on the spanwise-averaged overall cooling effectiveness.The coupling behavior among film cooling

impingement cooling

and deflected internal flow

as well as the flow resistance characteristics of the double-wall structures

are examined through analyses of dimensionless velocity

temperature

and streamlines.The results indicate that under reduced coolant requirements

a higher cooling effectiveness was achieved at a blowing ratio of 0.6；in the impingement chamber

a higher cooling effectiveness was observed near the stagnation region of the pin-fin

while the local effectiveness near the film hole side was reduced by flow separation；compared to pinless structures

pin-fin double-wall configurations exhibited higher velocities and more organized flow patterns；coolant outflow from film holes exhibited the best wall-attachment effect in the convex double-wall structure

while more outflow left the wall to enter the mainstream in the concave structure；at a blowing ratio of 0.6

the areaaveraged overall cooling effectiveness for the convex structure was 8.09% higher than that for the concave structure.This study is intended to provide theoretical guidance for the cooling design and performance analysis of curved turbine blade components with pin-fin double-wall structures.
