主动流动控制下载荷分离对进气道流场的影响研究
摘要
Abstract
In this paper,aiming at the problem of coupled load release and separation of internal and external flow in front of the inlet due to engineering constraints,the computational aerodynamic coupled six-degree-of-freedom model and dynamic nested grid technique are used to simulate the process of load release and separation,and the active flow control method is used to improve the flow field.The motion characteristics of load release separation of internal and external flow coupling with or without active flow control and its influence on the flow field of internal flow inlet are analyzed and evaluated.The results show that the distortion index DC(60)of the inlet can be reduced from 0.561 2 to 0.465 8 by active flow control,and the active flow control can improve the quality of inlet flow field.关键词
