Abstract

To improve the simulation efficiencies and accuracy of heat flow coupling of thermal barrier coatings (TBCs), a nozzle guide vane model with virtual TBCs was established, by equivalent series thermal resistance theory and virtual TBCs modeling method. The difference in heat flow and temperature on the nozzle guide vane surface with real and virtual TBCs was discussed and analyzed. The results show that if the thickness of TBCs is less than 0.5mm, the temperature distribution of the virtual TBCs model is basically the same as the real one, the maximum relative deviation is less than 5%. The thermal resistance of TBCs is affected by the thickness and installation position of TBCs, when the thickness is 0.5mm, the maximum and minimum heat resistance of the TBCs is 40? and 5?, respectively. The efforts of this study provide a framework to predict the heat flow coupling of TBCs.
