摘要
利用拉格朗日插值法建立了工程实际应用中的三维曲面插值模型,解决了利用有限元的方法进行发动机涡轮叶片温度场计算的边界条件问题。
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.
