Abstract:
     The low-noise aerodynamic nozzle comprises: a boss with a column cavity on front of the nozzle, and two or more micro-channels connected to the cavity around the boss. This invention changes flow field structure of nozzle jet to reduce large-scale eddy and the airflow noise, and destroys the sound feedback to reduce airflow impact noise.
