An integral boundary layer method based on the dissipation integral is used to account for viscous effects 考虑附面层影响，通过粘/位迭代得到跨音速翼/体的非定常气动力。
2 . the aerodynamics characteristics of this airfoil is studied in wind tunnel . this studies provides the direction of the research on boundary layer ( 2 )进行了翼型的低速气动力性能研究，为附面层特性研究提供了方向。
A numerical investigation about effects of boundary layer suction in low - speed compressor stator cascade with large turning angle was carried out 摘要本文采用数值方法研究了低速条件下附面层抽吸对大折转角矩形叶栅流场的影响。
The experimental investigations are performed on a three - dimensional boundary layer of a 45 degree swept back flat plate , which is subject to cross - flow instability <中文摘要> =本文对承受横流不稳定性的三维附面层进行了实验研究。
It is found to locate at the top of stationary vortex . considerable growth rate of the mode is found and is responsible for the transition of boundary layer 它出现在流向速度型的拐点处，有着非常大的增长率，并造成附面层的转捩。
The other occurs in lower location near to wall , which is interpreted as viscous instability and has growth rate similar to primary disturbance 该模态的增长率比基频及其谐波要大的多。另一个模态位于附面层的近壁处，属于粘性不稳定。
This demonstrates that for propulsion - airframe integration , this genus of inlet would be advantageous in keeping the stability of boundary layer coming from the forebody 一体化设计时，该进气道对保持前机体来流附面层的稳定性十分有利。
The investigated performance characteristics of lateral jet interaction include pressure fields , flow field pattern and surface pressure distribution with jet on or off in the streamwise direction . 2 本论文设计的计算程序具有模拟物体表面存在大压力剃度和激波与湍流附面层存在强烈干扰情况下的复杂涡流场计算的能力。
In recent decades , vortex generators used in separation control on wing boundary layer have developed rapidly . some new conceptions such as sub boundary layer , micro & intelligent vortex generators are coming up 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。
By choosing reasonable suction location and combination , the large scale profile separation can be well controlled , but the effect on decreasing the secondary flow loss is limited 计算结果表明，通过选用合理的抽吸位置及抽吸方式的组合，附面层抽吸能较好地控制叶栅内的大尺度的叶片表面分离流动，但对二次流损失的改善效果并不明显。
