异向/同向转子密炼机中物料流动和炭黑分布情况的数值模拟与试验研究

Numerical Simulation and Experimental Study on Compound Flow and Carbon Black Distribution in Counter-/Co-rotating Twin Rotor Mixer

对异向/同向转子密炼机中物料流动及炭黑分布情况进行数值模拟和试验研究。结果表明,转子的旋向对炭黑在胶料中的分布有显著的影响,与异向旋转相比,同向转子密炼机初期的分布能力较低,但最终分布效果略优。数值模拟可对胶料在密炼机中的流动分布情况进行可视化研究,为转子性能的模拟测试提供了新方法。

Compound flow and carbon black distribution in counter-/co-rotating twin rotor mixer were numerically simulated and experimentally investigated. The results showed that,the rotating direction of the rotors had a significant effect on carbon black distribution in the compound. Compared with counterrotation,the distribution capacity of co-rotating twin rotor mixer was lower in the early stage,but slightly better at the end. Numerical simulation could conducted a visual study on the flow and distribution of compound in mixer,which provided a new solution for analog test of rotor performance.
