SIMULATING THE AIR-FLOW FIELDS OF DIFFERENT SPUNBONDING DRAWING CONDUITS

ABSTRACT
The air-flow fields of different spunbonding drawing conduits are modeled and simulated numerically. Simulated results are compared with the measured results and show good agreements with the latter. Results show that a larger narrow length and a larger contracting length can produce a higher air velocity, which is beneficial to the polymer drawing. This research is valuable to the optimal design of the spunbonding drawing conduits.
