| Abstract: | New approach to a simulation of single and twin screw extruders for thermoplastics processing was suggested. The approach
takes into account real boundary geometric conditions and conditions on velocity (a screw is rotated, cylinder is fixed),
and also that there exist phase transformations of the processed material and its heat exchange with surfaces of the screw
and cylinder limiting the working channel of the extruder. |
