Thermal fatigue (TF) is one of the most important factors that influence turbine’s life. This paper establishes a 3D solid-fluid coupling model for a steady temperature analysis of a high-pressure turbine nozzle at different turbine inlet gas total temperatures (TIGTTs). The temperature analysis supplies the temperature load for subsequent 3D finite element analysis to obtain the strain values. Following this, the prediction of the TF life is made on the basis of equivalent strain range. The results show that the strain increases with TIGTT, and the predicted TF life decreases correspondingly. This life prediction was confirmed by one TF test.
