摘要:
运用数值模拟法，对双转子连续混炼机混炼段的剪切应力 进行模拟计算和分析。结果表明：沿转子轴向和垂直于轴向截面上的剪切应力分布合理，剪 切应力体积分数分布合理。转速增加，剪切应力随之增大，单位产量平均剪切应力增大。轴 向压差增加，剪切应力层状分布形态明显改变，单位产量平均剪切应力增大。加料量增加， 剪切应力大小和分布形态不变，但单位产量平均剪切应力随之减小。利用这3种可调工艺参 数的不同作用特点，针对不同的混合需要，可计算和选择不同的工艺参数组合。
Abstract:
The shear stress in the mixing process of the double roto r continuous mixer is analyzed and calculated by means of numerical simulation. The result indicates that the shear stress at axial section and vertical section of the rotor and its volume fraction distribution have the proper distribution. The shear stress and the average value of the shear stress of production per un it increase as the rotor speed increases. The form of the layered distribution o f the shear stress changes distinctly and the average value of the shear stress of production per unit increases as the pressure difference in axial direction i ncreases. The increase of the feeding capacity has no influence on the value of shear stress and its form of the layered distribution, but the average value of the shear stress of production per unit decreases. Different combination of tech nologic data can be calculated and chosen according to different mixing requirem ent and the special operational characteristic of the above three adjustable tec hnologic data.
