Active Flow Control is a technology used to manage and optimize the flow of fluids, such as air or water, in various systems. It involves the use of sensors and actuators to dynamically adjust flow conditions, improving efficiency and performance. This technique is commonly applied in fields like aerospace, automotive, and HVAC systems. By actively controlling the flow, systems can reduce drag, enhance cooling, and improve overall energy efficiency. For example, in aircraft, Active Flow Control can help maintain lift and reduce fuel consumption, while in HVAC systems, it can lead to better temperature regulation and comfort.
