Introducing a new element rotational barrel segment (RBS) into construction of single
screw extruder (SSE), significantly changes the kinematic of motion in SSE. Main goal of
incorporating RBS into SSE construction is to improve output and mixing capabilities. To
evaluate three types of RBS geometries, CAE analysis was performed with ANSYS
POLYFLOW® software. Evaluation of three different RBS geometries at three different
movement states (static, screw co-rotating and screw counter-rotating) provided detailed insight
in flow phenomena occurring in melted polymer during passing through RBS. CFD simulation
of melt flow in SSE allows analyzing various processing conditions, screw geometries and even
complicated kinematic couples as screw-RBS.
