Summary

The jet is also called the free jet, the steady jet, or the continuous jet, and is one of the conventional flow control techniques used for boundary layer flow control. The fundamental control mechanism is that the jet can enhance momentum mixing between inner and outer boundary layer, which is beneficial for separation delay. In addition, the jet can be used as an approach for circulation control, which can increase the lift coefficient significantly. Thus, the jet has been widely tested in airfoils, wings and aircraft for flow control. Also, the interaction of the jet with free stream can simulate the function of some conventional passive techniques, such as the vortex generator and Gurney flap. However, in comparison with passive techniques, the control techniques based on the jet can be conducted in real-time and unsteady control, which is more robust. Thus, jet flow control shows great potential applications in engineering.
