Description
Summary:An analysis software for intermeshing modular corotating twin screw extruders was developed. A global computation model was incorporated in analysis software. The development of the composite model simulation of solids conveying, melting, and melt flow in a modular corotating twin screw extruder is described. We discuss the applications of simulation which predict axial fill factor, pressure, temperature, torque, power consumption, specific energy consumption, and average residence time. Design analyses for modular corotating twin screw extruders with multiple ports are presented for the various processing conditions. The results are compared for different size of machines. These computation results can assist the process-designing engineer in the optimization of an extruder design and operation parameters for various usage of machine.
