| 摘 要： | 本文在文献[1]和文献[3]的基础上对无锡动力机厂提供的11GJ及110J型涡轮增压器离心式压气机叶栅S_1流面的气动特性进行计算。计算结果分析表明:110J型叶栅气动特性优于11GJ型叶栅,与实际试验所得结果——110J型效率(74%)高于11GJ型(72%)相吻合。文章对出气角β_2、分流片环量Γ_I及栅后区长度的选取等提出自己的观点,尤其对难以估计的出气角β_2作了较详细的论述,且经多种涡轮、压气机和风机等叶轮机械的实例计算均行之有效。

| Abstract: | Based on the variational principles and the work, aerodynamical calculation was presented for the blade-to-blade flow on S_1 stream sheet of centrifugal compressor (Type: 11GJ and 110J). The calculation shows that the efficiency of Type 110J (74%) is greater than that of Type 11GJ (72%). The result is fully in agreement with that of the experiment performed by the Wusih Power Machine Plant. |
