Numerical simulation of airflow behaviour and nozzle ...
The texturing performance enhanced when the L/D ratio of yarn channel was between 7 and 10, and the ratio of the cross-sectional area of air inlet to the yarn channel was 1/4th. The use of air inlet at an angle between 45° and 60° with a 10° divergence provided at the exit side of the yarn channel further enhanced the texturing process [ 6 ].
