Flow patterns in the calender gap of a counterrotating twin screw extruder
Abstract
Abstract The finite element method was employed to examine the flow details in the calender gap of a counterrotating twin screw extruder. For Newtonian fluids a vortex is predicted at the entry of the calender gap. Calculations show that the vortex intensity is determined uniquely by the value of relative throughput and disappears when it exceeds 24%, for the geometrical configurations examined. Shear thinning behavior of the fluid reduces the …
