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

激波/边界层干扰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，使用压电襟翼致动器来控制相互作用。目的是参加剑桥大学工程系利用纵向槽进行SBLI控制的实验方案，该工程系是SBLI控制的一个主要国际机构。它们的纵向槽控制与单压电晶片控制非常相似，因此本研究可用于提高对单压电晶片控制的理解。此外，他们的CFD程序可以验证我们过去的工作，并允许理论优化，以创建智能襟翼系统。

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.
