近十年来,用于飞机机翼附面层分离控制的涡流发生器发展很快,出现了亚附面层、微型和智能化涡流发生器等新概念。 - Finally , the two dimensional flow in the diffuser is calculated , the results show that the change of ma makes an effect to the performance of the diffuser . owing to the accretion of ma , the action of oblique shock waves and the boundary layer pricks up , the flow separates from the wall where the shock waves impinge on the boundary layer more quickly , the cluster of diamond shock waves becomes larger . moreover , by comparing the change of flow field under different structure parameter , it is found that the augment of length of constant area section alter the structure of fluid field little , a smaller area ratio and larger angle of compression section make the diffuser working better
最后,针对扩压器中的二维流场进行了数值模拟,结果表明马赫数对扩压器性能影响较大,随着马赫数的增大,扩压器管道内激波-附面层干扰加剧,流动从附面层分离相应加剧,激波串数目增多;通过比较不同结构参数下的扩压器内流场,发现等直段长度的变化几乎没有改变流场结构,只是对局部流场稍有影响,并且在其它参数不变的情况下,一定范围内减小面积比a2 / a1和增大收缩角有利于扩压器性能的提高。 - 3 . the characteristics of boundary layer ' s transition , shape and separation are researched . the details as follows : ( l ) airfoil surface is turbulent boundary layer flows ; ( 2 ) velocity figure changed unsteady near the point of boundary layer separation due to randomicity of turbulent flow ; ( 3 ) the airfoil have better state of boundary layer separation and poor stall characteristics because of the upper surface of airfoil is flat
