摘要
文章利用计算力学和有限元法,基于大型模拟软件ANSYS-CFX对开槽三头捏合块双螺杆流场模型混合段进行三维流场分析。通过对流场速度场、压力场、剪切速率场、加权平均剪切速率等进行计算分析,并与未开槽捏合块流场对比,发现开槽捏合块比常规啮合块对挤出机中物料具有更好的混合能力。
Three slotted screw kneading block mixing section of three-dimensional tlow fieht were sim- ulated with compulalional mechanics and finite element method, based on large-scale simulation soft- ware ANSYS-CFX. By convection velocity field, pressure field, shear rate field, the weighted average mass lloyd, calculated and analyzed, and compared with no slol of the kneading bloekh found that the grooved kneading block of the extruder block malerial had betler mixing capabilities than conventional engagemenl.
