Description
  • Jet nozzle with tangentially injected airflow has been applying into spinning technology due to the tangential force produced by swirling airflow. In order to understand the airflow motion trajectory in jet nozzle and modify the nozzle structure and dimension, FLUENT software program is used. Some parameters which are closely related the airflow motion profiles are studied, such as the diameter of nozzle chamber, the diameters and angle of orifice. The results showed that the velocity distribution in significantly related to fluid flow and consequently to yarn properties. With increasing in the orifice angle, the tangential velocity increases but the axial velocity decreases somewhat; with increasing in the orifice diameter, the mass flow rate and the velocities distribution changes; with increasing in nozzle chamber, the axial and tangential velocity decreases somewhat.
