CONJUGATE HEAT TRANSFER INVESTIGATION ON COOLING PERFORMANCE OF AIR-COOLED TURBINE STATOR BLADE
For aero-engines,stator blade is a key component,which is important to increase thermal cycle efficiency.In this paper,a calculation model using conjugate heat transfer(CHT)method was established for an aircraft engine firstlevel turbine stator blade with air cooling,and 3D heat transfer simulation considering the radiative influence was accomplished,which caused the computed results to be more reasonable and accurate.The first-level turbine stator blade channels flow field temperature distribution and the stator blade surfaces temperature distribution were obtained in three different working states: the max-power state,the cruise state and the idle-power state.On this basis,the research to the cooling performance of the turbine air-cooled stator blade was conducted.The results provided the basis for material feasibility analysis of the turbine stator blade,and the calculation method was of high value on engineering application.
