几种关于附面层分离主动控制方法机制的概述

随着飞机和发动机设计性能要求的不断提高,流体的主动控制变得越来越重要,并显出不可替代的作用。流体主动控制方式通过小尺度、局部的能量注入,特别是通过对临界点附近的控制来改变全场的流动结构,并且能够对复杂的动态系统进行精确的相位控制,所以在近年的流动控制领域变得非常活跃。本文对合成射流、等离子体、电磁体积力这些主动控制方法及其机制进行了详细的介绍,并得出结论：相对于被动控制方式,主动控制方式具有明显的优势。

Overview of Active Control Mechanism of Techniques in Boundary Layer Manipulation

With the advancement of aircraft and aeroengine performances,active controls in boundary layer separation play an important role and become irreplaceable.Through its small-scale and partial energy injection,especially control of near critical point,flow structures could be greatly manipulated.The accurately phase control in complex dynamic system has been received more and more research interests in recent years.Synthetic jet actuator,plasma technology and electromagnetic force are introduced in detail in t...
