| 摘 要： | 通过求解N—S方程对流场进行数值模拟，已成为研究透平机械的一个重要手段。而建立合适的转捩模型能够使流场数值模拟更为准确。本文作者利用现有的试验数据对Abu—Ghannam and Shaw^[1]转捩模型(AGS转捩模型)进行了修正，提出了利用弧长雷诺数模型确定转捩区长度的思想，并对计算结果与试验值进行了比较。

| Abstract: | Numerical simulation on the flow field by calculating N-S equation has become an important means for study on the turbomachinery,and the establishment of appropriate transition model enables the numerical simulation more accurate.The author modified the Abu-Ghannam and Shaw Transition Model (AGS Transition Model) with ready test data,set out the concept of calculating the transition length with arc Reynolds number and compared the calculated value with the test value. |
