Abstract
The flow in a pin-barrel extruder has been analyzed based on a Newtonian fluid model. A numerical simulation based on the FAN method of Tadmor and his coworkers and an analytical model were used. The calculations show that the introduction of slices into screw flights and pins make the apparatus a much poorer screw pump. It would appear that the machine is though an effective continuous (distributive) mixing device.Keywords
