| Abstract: | Three-dimensional flow simulations of combined element, including flight elements and kneading blocks in an intermeshing co-rotating twin screw extruder is performed by ANSYS.Pressure and velocity profiles are obtained.Effects of kneading blocks,screw elements,and combined runners in mixing are analyzed by comparing flight elements,kneading blocks and combined elements. |
| Keywords: | intermeshing co-rotating twin screw extrusion combined runner flow field analysis |
