一、测试设备和测量技术 用单根斜热丝探测文献[1]介绍的压气机静叶排的“轮毂处理”装置附近的动、静态流动特性,对了解它产生效果的机理有很大意义。为了实现测量,设计了图1所示的位移机构。
I. TESTING EQUIPMENT AND MEASURING TECHNIQUES The dynamic and static flow characteristics near the “hub treatment” device of the compressor vane row introduced in [1] are examined with a single oblique heat filament to understand the mechanism by which it produces an effect . In order to achieve the measurement, the displacement mechanism shown in FIG. 1 was designed.
