摘　　要：运用ANSYS/CFX对具有反向捏合块元件的啮合同向双螺杆挤出机的流道进行流场分析,研究分析豆粕在其流道中的运动情况,包括速度矢量图、速度流线图、宏观压力图,并和具有普通双螺杆元件挤出机进行对比分析。结果表明:由于反向啮合块的存在使得双螺杆元件的分布混合性能以及分散混合性能大幅度提高。研究结果可为双螺杆挤出机加工提供参考。Using CFX method to analyze material flow field of twin-screw extruder which with a reverse kneading. Study and analysis of the movement of soybean meal in its channel. Including the velocity vector, velocity flow charts, macroscopic pressure field. The twin-screw extruder with reverse kneading was compared with those of ordinary twin-screws. The results indicated that with the help of reverse kneading, the distribution of soybean meal in the twin screw extruder and the performance of the mixed hybrid were greatly improved. The research could provide reterences for twin screw extruder processing.
