Abstract:

The influence of outer length on air flow field in melt blowing with dual slots was studied by numerical simulation. Firstly, two accessories with certain length were added to the outside of dual slots in the melt blowing die. Then, the air flow field of the melt blowing with dual slots added with the accessories was studied by numerical simulation. Finally, the influence of the outer length on the air velocity and pressure and temperature distribution on the spinning center line was anslyzed. The results showed that when the length was increased gradually, the maximum values of air velocity and pressure decreased, but that of the temperature remained unchanged substantially, and the decrease degree of air velocity and pressure increased, but that of air temperature decreased.

Key words: numerical simulation, melt blowing, accessory, outer length, air flow field
