| 摘 要： | 本文对某高性能常规涡轮开展了对转改型研究。首先对该常规涡轮进行基本分析,详细探讨了将其改进为1+1及1+1/2对转涡轮(无低压涡轮导叶)时遇到的关键问题,并给出了一些解决问题的方案.研究表明,1+1对转方案现实可行,1+1/2对转方案将很难实现.在方案研究的基础之上,本文进行了保留过渡段的1+1对转涡轮详细设计并采用三维黏性程序对其性能进行了初步的分析。

| Abstract: | Using counter-rotating technology to modify a high performance conventional turbine is investigated in this paper.The basic analysis of the conventional turbine performance is taken out, then the key problems in the modification process,which include the conventional turbine modifying to a 1+1 and a 1+1/2 counter-rotating turbine,are discussed in detail,and some proposals of modification are given in this paper.The results show that the modification from the conventional turbine to a 1+1 counter-rotating tu... |
