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 growth. The focus of the proposed research is to investigate the fundamental flow dynamics of separated and wall-bounded shear layers, and how such phenomena can be manipulated to improve flow characteristics in order to reduce drag and harmful emissions. The overarching aim is the development and implementation of active flow control strategies, either open or closed-loop, in an experimental framework, with a view to deployment in industry.

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一个关键因素，以产生所需的范式转变，以满足日益严格的环境标准的排放，同时保持增长。拟议的研究的重点是调查分离和壁约束剪切层的基本流动动力学，以及如何操纵这种现象，以改善流动特性，以减少阻力和有害排放。总体目标是在实验框架中开发和实施开放或闭环的主动流量控制策略，以便在工业中部署。
