High-Fidelity Large-Eddy Simulation of a Pulsed Jet Actuator
摘要
Pulsed jet actuators (PJAs) are a type of fluidic oscillators that can be served as an active flow control device on lifting bodies. PJAs are able to provide an unsteady periodic blowing in a wide frequency range, which adds momentum to the boundary layer to prevent separation, and thereby enhancing the aerodynamic performances [2]. This kind of fluidic oscillator has no moving parts and induces the oscillation using only its internal unsteady flow dynamics, which makes it attractive for applications given its robust design and installation [9].
