概要

• 論文の詳細を見る

• A novel coaxial jet nozzle equipped with a row of miniature electromagnetic flap actuators on its outer lip of the annular nozzle is developed for active mixing control. The spatio-temporal flow structures of the controlled jet discharging into an expanded circular duct are studied through flow visualization and quantitative measurements by using laser Doppler velocimetry and laser induced fluorescence. It is found that the large scale vortical structures emerging from the shear layer between the annular jet and the ambient fluid is significantly strengthened with the artificial disturbances generated by the flaps. The mixing between the inner and outer jets are markedly enhanced through the vigorous pinching of the central fluid.
