Active flow control is a research area focused on developing methods to manipulate and control fluid flow in a variety of applications, such as aerodynamics, hydrodynamics, and combustion. This can involve using actuators, sensors, and control algorithms to influence the flow of air or liquid in order to improve performance, reduce energy consumption, or enhance safety. Active flow control can be used in a wide range of industries, including aerospace, automotive, and maritime, and is an important area of study for improving the efficiency and effectiveness of various systems and processes.
