| 摘 要： | 首先进行了带进口热斑的涡轮级S1流面非定常计算.在此基础上,通过一些假设条件,提出分段计算和积分计算两种简化的热斑迁移路径分析方法.与非定常计算结果的对比表明:这两种方法在预测热斑迁移路径上具有较高的精度,对热斑通过涡轮级的周向偏移量计算偏差在1°以内.

| Abstract: | An unsteady numerical simulation of turbine stage on the S1 flow surface with hot streak was performed firstly.After analysis of the results,some assumptions for the hot streak migration were made.And then a separate section calculation method and an integral calculation method for the hot streak migration avenue were presented.Comparison with the unsteady calculation,the results show that,these two methods have high precision on the prediction of the hot streak migration avenue,and the differences of migration in circumferential direction are within one degree. |
