  • 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.
