Active and Passive Techniques of Shock Wave/Boundary Layer Interaction Control

激波/边界层相互作用（SBLI）是高速空气动力学中的一个难题。我们研究了一种新的方法，使用压电襟翼作动器来控制相互作用。目的是参加剑桥大学工程系的一个利用纵向槽控制SBLI的实验项目，剑桥大学是SBLI控制的国际领先机构。它们的纵槽控制与匀形控制非常相似，因此本研究可以用来提高对匀形控制的认识。此外，他们的CFD程序可以验证我们过去的工作，并允许理论上的优化来创建智能襟翼系统。

The shock wave/ boundary layer interaction (SBLI) is a formidable problem in high-speed aerodynamics. We investigate a novel method, using piezoelectric flap actuators to control the interaction. The aim is to participate in an experimental programme on SBLI control using longitudinal slots at The University of Cambridge's Engineering Department, a leading international institution for SBLI control. Their longitudinal slot control is very similar to unimorph control so that this research can be used to improve the understanding of unimorph control. Furthermore, their CFD program can validate our past work and allow theoretical optimisation to create a smart flap system.
