Numerical Simulation of the Inner Flow Field of Hema-Type ATY Nozzle Based on Fluent

The characteristics of air flow inside the inner channel of a Hema-type ATY(Air-Textured Yarn) nozzle were simulated based on the geometrical model of the inner channel built up usingPRO/E and the turbulent air-jet with a standard k-ε model simulated using Fluent．The simulation revealed that the ideal air in equivalent temperature came to channel while the flow pressure reached to the minimum．The results visually demonstrated the flow field of the inner channel of Hema-type ATY nozzle．And it could be a valuable reference for optimizing parameter on the Hema-type ATY nozzle.
