| Abstract: |
| By professional viscoelastic fluid software（Polyflow），the mixing process of compound with or without ultrasonic-aided condition was simulated to study the effect of ultrasonic on the dispersion，distribution and flow of the compound.The results showed that，under ultrasonic-aided condition，the time for the pressure and concentration of the flow field to reach their peaks was shortened，the particle dispersion speed was accelerated，shearing action of the compound in the gap between the tip of the rotor screw flight and chamber body was enhanced，and the viscosity at screw flight was reduced，which could facilitate the distributed mixing of rubber and additives in two cavities，and accomplishe the dispersion and mixing process faster to improve the efficiency of mixing and compound quality significantly. |
