| 摘 要： | 采用有限差分数值分析方法，应用温度逐次更新处理技术对不同扰流孔下的椭圆管矩形翅片的肋效率进行计算。结果表明，采用当量椭圆简化矩形翅片使肋效率偏高，增加扰流孔则导致肋效率下降。

| Abstract: | The FDM numerical analytic method is applied to calculate the fin efficiency of elliptic tube with rectangular fins on which the disturbing holes were dug by using additional source term technique.It shows that the calculation by applying equivalent ellipse will produce a value of fin efficiency on the high side and the fin efficiency decreases with the increase of disturbing flow holes. |
