Abstract

Laser Doppler Anemometry (LDA) was used to map velocity distributions in the nip region of a co-rotating twin-screw extruder. Axial and normal components of velocity were measured at 90 rpm for heavy corn syrup in a section having a reverse element between forward conveying elements. Flow towards the hopper was seen only in the nip region of the reversing section. The flow was seen to adjust to the change in direction of pitch within 4-5 mm, axially.
