摘要
应用多普勒激光测速法测量同向旋转双螺杆挤出机捏合区域的速度分布。在90r/min分的转速下，测量两螺杆捏合区中推力区和阻力区熔体的轴向速度和法向速度。
：Laser Doppler Anemometry was used to map velocity distributions in the nip region of a co-rotating twin-screw extruder.Axial and normal components of velocity were mersured at 90rpm in a section having a reverse element between forward conveying elements.
