本文介绍了旨在模拟压缩机内部管道排气槽的新测试设备的调试。它还首次确定了冰晶粒径在冰晶现象中起着重要作用。提供了接近冰点的湿球温度下的吸积数据和样本图像。研究了湿球温度和颗粒尺寸对冰晶自然融化的影响。此外，还讨论了冰晶颗粒对表面沉积物的侵蚀。
This paper describes the commissioning of a new test apparatus intended to simulate an inner-compressor duct bleed slot. It also identifies, for the first time, that ice crystal particle size plays an important role in the ice crystal phenomenon. Data and sample images of accretion are presented for wet bulb temperatures near freezing. The effect of wet bulb temperature and particle size on the natural melting of ice crystals is investigated. In addition, the erosion of surface accretion by ice crystal particles is discussed.
