三角排列三螺杆挤出机（TATSE）是一种新型的挤出机，它具有不同于双螺杆挤出机的特殊结构。采用有限元法模拟了TATSE内部的三维非等温流动。重点研究了不同转速、螺杆飞行数、压差和流量下TATSE的温度分布、功率消耗和生产率比。对双螺杆挤出机（TSE）、并联布置三螺杆挤出机（PATSE）和TATSE三种挤出机的功率消耗和生产率比进行了比较分析。结果表明，TATSE的混频特性和功率特性优于TSE和PATSE。
A triangle arrayed tri-screw extruder (TATSE) is a new-style extruder that has a special structure different from a twin screw extruder. Three-dimensional and non-isothermal flow in TATSE was simulated by using the finite element method. The temperature distribution, power consumption and productivity ratio in TATSE at various rotational speeds, screw flight number, pressure difference and flow rate were studied especially. Comparison and analysis of power consumption and productivity ratio between twin screw extruder (TSE), parallel arranged tri-screw extruder (PATSE) and TATSE were carried out. The results show that the mixing and power characteristics of TATSE are better than those of TSE and PATSE.
