摘　　要：运用ANSYS/CFX对豆粕在带有混炼区的双螺杆膨化机中进行流场分析,研究分析物料在其流道中的运动情况,包括速度场、宏观压力场,并和普通螺杆进行对比分析。结果表明混炼区的存在减缓了物料速度,打乱物料的速度流线,延长物料在机筒内的时间,有利于物料混合。研究结果可为双螺杆膨化机加工提供参考。The flow field analysis of soybean meal in a twin-screw extruder with mixing zone was made by using ANSYS/CFX,The material movement in the flow channel was researched,including velocity vector,velocity flow chart,macro stress map,and then these were compared with ordinary screw.The presence of the mixing zone slowed the material speed,disrupted the material velocity streamline,extended the time of material in the barrel.It benefits for materials mixing.The research could provide references for twin screw extruder processing.
