Abstract
Flow separation and wind gusts affect the aerodynamic performance of low-Reynolds number flyers with a chord-based Reynolds number of 105 or below. Active flow control provides information into fluid dynamics as well as potential vehicle performance enhancements. Aircraft engines, as well as stationary flow devices, exhibit undesirable flow states that have a significant impact on noise output and aerodynamic loss. Vibrations and aerodynamic performance are likely to suffer as a result of flow and boundary layer separations. Flow management can be an effective approach for lowering noise levels, increasing efficiency and thereby lowering fuel usage. Various forms of flow can be controlled using both passive and active flow control strategies. The active alteration of aerodynamic flows utilizing small time-dependent actuators in well-chosen places is defined as adaptive flow control. Micro-adaptive flow control has a significant overall system benefit in a variety of large-scale applications, which are presented.
