Based on the new phenomena of pellet melting in single screw extrusion,the physical-mathematical model which reflects permeating exertion in initial stage of the melting zone was set forward with the aid of macroscopic and sub macroscopic visualization.

The melting model of the broken solid pieces in the later stage of the melting zone in the process of the single-screw extrusion is firstly established, and the equation calculating temperature field of broken solid pieces is mathematically deduced.

Experimental Study on Melting Process in Vibration Induced Single Screw Extruder;

Numerical simulation of three-dimensional flow in single screw extruder by finite volume method;

Based on finite difference method of numerical simulation, the semi-analytical method is proposed in the paper, which is adapted to compute the residence time distribution(RTD) of polymer melt in a single screw extruder, then the RTD under different operation parameters are obtained to characterized the mixing of polymer melt in the course of processing.

Devolatilization of hydroxyl-terminated polydimethylsiloxane in single-screw extruder;

With the foundation of the extrusion theories of a single-screw extruder,use for reference to research results of design theories of twin screw extruders in plastic industry and twin screw bulking extruders in food industry,to study design theories thoroughly of the TSPE is still need to know the particularity of .

Based on the study on auger delivery theory of retarded adhesive mortar and the statistics of flow field in the single-screw extruder,the flow in extruder is simulated by using ANSYS software and taking a spiral length as the object.
