| 摘 要： | 以高温透叶片尾部区内部冷却为应用背景，对带顺排、错排扰流片肋的通道内空气流动和传热过程进行了数值模拟。计算结果表明，在相同雷诺数下，错排扰流片的阻力系数比针肋和顺排绕流片的阻力因子均增大约2%，而冷却能力分别增大约50%和9%。

| Abstract: | With the internal cooling of the trailing edge of high temperature turbine blade as the application background, the flow and heat transfer process was computed in the duct with sequence and staggered rectangular fins. The computational results indicate that the rectangular plate fins are better than pin fins for heat transfer enhancement. With staggered rectangular fins, the flow resistance factor rises about 2% compared with the duct with sequence rectangular fins and pin fins under the same Re , whereas the cooling capability rises 9% and 50% respectively. |
