| 摘 要： | 作者设计了 4种主流倾斜的引射器模型,分别在 5种主气流倾斜角和 4种排气反压下,完成了模型冷流试验。试验表明,4种模型中具有等直管的模型 3,4引射系数普遍高于大头模型 1,2。在零气流角和反压为大气压时,约高 10%左右,最高引射系数为 3.379。试验还表明,具有等直管的模型3和模型4能承受的反压较大。引射系数 N为零的反压可高至 900mm水柱左右。 4种引射器模型中,模型 4的综合性能最好

| Abstract: | Four ejector models designed with changeable main flow angles were investigated experimentally under four back pressure and five flow angles.The results indicated that the ejection coefficient N of the model with constant cross section was higher than the model with diffusion inlet.The maximum N of 3.379 was measured from model 4.It was found that the model 4 has a favorable performance among the tested four models. |
