流动控制可应用于激波/边界层干扰以实现两个不同的目标;激波诱导分离的延迟和/或引起波阻或进气道效率低下的滞止压力损失的减少。本文介绍了这两种方法的原理和主要技术，并评估其相对适用于实际应用。虽然边界层抽吸已经广泛用于分离控制，但最有前途的新型装置是微型涡流发生器，它可以在大大降低装置阻力的情况下提供与传统涡流发生器类似的好处。由于多种原因，冲击控制尚未用于实际应用，但最近的研究集中在三维装置上，这些装置有望提供具有改进的非设计行为的流动控制。此外，有一些迹象表明，新一代控制装置可能能够将激波和附面层控制的优点联合收割机结合起来，减少激波引起的滞止压力损失，并延迟激波引起的分离。
Flow control can be applied to shock wave/boundary layer interactions to achieve two different goals; the delay of shock-induced separation and/or the reduction of stagnation pressure losses, which cause wave drag or inlet inefficiencies. This paper introduces the principles and main techniques for both approaches and assesses their relative suitability for practical applications. While boundary layer suction is already in wide use for separation control, the most promising novel device is the micro-vortex generator, which can deliver similar benefits to traditional vortex generators at much reduced device drag. Shock control is not yet used on practical applications for a number of reasons, but recent research has focused on three-dimensional devices which promise to deliver flow control with improved off-design behaviour. Furthermore, there are some indications that a new generation of control devices may be able to combine the benefits of shock and boundary layer control and reduce shock-induced stagnation pressure losses as well as delay shock-induced separation.
