Plasma actuator for model-based feedback control of transition in laminar boundary layers

最近，运输业，特别是航空业受到越来越大的社会和政治压力，要求它们减少对环境的影响和对全球变暖的贡献。主动流量控制已被确定为产生范式转变的关键因素，所述范式转变需要满足日益严格的排放环境标准，同时维持经济增长。拟议的研究的首要目标是调查基本的流体力学，动力系统和控制问题，以改善流动特性（如低阻力）通过反馈控制。本建议的主要重点是有关的驱动问题，目的是取消不稳定性，导致旁路过渡层流边界层。此控件将使用

Recently, there has been an increasing amount of social and political pressure placed on transport industries, in particular aviation, to reduce their impact on the environment and contribution to global warming. Active flow control has been identified as a key factor to produce the paradigm shift required to meet increasingly stringent environmental standards on emissions, while sustaining economical growth. The overarching aim of the proposed research is to investigate fundamental fluid mechanics, dynamical systems and control issues in order to improve flow characteristics (e.g. lower drag) via feedback control. The primary focus of the present proposal is concerned with actuation issues for the purpose of cancelling the instability that leads to bypass transition in a laminar boundary layer. This control will be performed using an array of
