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