| Abstract: | A numerical method was presented to load thermal boundary conditions onto surfaces of twist blade. The loading of thermal boundary conditions was achieved by using a three - dimensional interpolation model, that is, the LAGRANGE formula is performed to interpolate along span wise and stream wise orderly. Calculated results were presented for a typical vane, and those showed effectiveness and reasonable temperature distribution. |
