Abstract:

The fluid mix during the polymer melt conveying under the effect of vibration in a standard metering screw channel was numerically investigated, and the melt conveying under the effect of vibration was calculated and simulated by using the computational fluid dynamics （CFD） software Polyflow. Moreover, the stretching rate of the fluid reflecting the effect of distributing mix was analyzed via statistical analysis. Statistical results indicate that the vibration force field helps to enhance the homogenization of the melt and to improve the effect of distributing mix, and that, in the simulated frequency range, the mix degree improves with the vibration frequency up to an optimal value.
