In this paper we report on the investigation of hairiness control using nozzles at ring frame. Airflow simulation inside the nozzles givessome insight into the mechanism of hairiness reduction. To solve the three-dimensional airflow field inside the nozzles, a CFD (computational fluid dynamics) model has been developed to simulate the airflow pattern using FLUENT 6.1 software.
