| 摘 要： | 本文对任意形状的曲面边界层,采用了局部相似性解法,将二元曲面分成若干段,把每一段看成一个楔形体的斜面,并将相似性解用于每一线段,求解后再沿曲面积分,便可得到问题的解答。实际计算表明,这种方法是行之有效的。1 问题的提法 对于给定的翼型,已知来流速度U_∞ =100m/s,Re_∞=6.85×10~5,同时表1和表2分别给出翼型的几何尺寸和势流速度分布,要求计算翼型的摩擦阻力和摩擦阻力系数。

| Abstract: | The partial similarity method is used for the calculation of a boundary layer with a curved surface of arbitrary shape. The two-dimensional curved surface will be divided into several parts. For the curved surface as a whole there is no similarity solution, but for each individual part, there is. This is exactly what is meant by partial similarity solution. Actual calculation shows that this method is feasible, and if some details in the calculation are improved, the accuracy can be even higher. |
