| 摘 要： | 计算并分析了高马赫数情况下,直叶片及正弯20°叶片在攻角分别为0°、±10°、±20°及±30°的情况下的流场结构. 采用的数值方法为具有TVD性质的三阶精度GODUNOV格式,湍流模型为B-L代数模型. 计算结果表明,在较大的攻角范围内,正弯叶片可以减小叶栅流道内通道涡的强度,并且由于两端壁的附面层被吸入主流,使得正弯叶片中的能量损失减小. 攻角越大,正弯叶片的作用越明显.

| Abstract: | The article believes that the problems of operational efficiency and development of enterprise capitals have not been resolutely solved in the process of state - owned company reform in China. Enterprise system as a whole should be optimized among which property right system, share structure, legal person management and property share stimulation play critical roles. The author probes into the problems and advances some measures. |
