... measurements acquired at the HPT exit to predict the turbine inlet temperature and nonuniformity magnitude. The proposed method utilizes a multiwavelet approximation technique to extract the hot-streaks-related component at the HPT exit, which is then used to approximate the HPT inlet temperature distribution...

...Fangyuan Lou In gas turbine engines, the temperature field at the exit plane of the combustor is highly unsteady and complex, with large radial and circumferential variations. The circumferential temperature variations (hot-streaks) are caused by the discrete nature of fuel and dilution air jets...
