Simulation of airflow motion in jet nozzle with different geometric parameters
Original language 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, 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 diameter and angle of the orifice. The results showed that the intensity of air swirling is more strong in a smaller nozzle chamber; a larger orifice diameter is helpful for producing strong yarn and improving production efficiency, but it requires a larger nozzle chamber, therefore, a reasonable rate of orifice and nozzle chamber diameter isimportant; as the orifice angle increases, the tangential velocity decreases, which decreases the intensity of airflow swirling, and a small orifice angle will cause a larger reverse jet, which is bad to draw the fibers into the nozzle.
