Determination of the degree of fill in a counter-rotating twin screw extruder

Modeling of Transport Phenomena and Melting Kinetics of Starch in a Co-Rotating Twin-Screw Extruder

A mathematical model was developed to simulate fluid flow, heat transfer, and melting kinetics of starch in a co-rotating intermeshing twin-screw extruder (TSE). The partial differential equations governing the transport phenomena of the biomaterial in the extruder were solved by a finite element scheme. For validating the model, the predicted product pressure, bulk temperature at the entrance ...

Continuous Granulation with a Twin-Screw Extruder

Simulation of Distributive and Dispersive Mixing in a Co-rotating Twin-screw Extruder

Simulation results for mixing of two different polymers in a co-rotating twin-screw extruder are presented. Velocity distribution predicted by a threedimensional simulation of the flow is used to predict the change in the spatial distribution of initially segregated particles as well as the reduction in radius due to erosion. The predicted particle distribution is used to estimate the increase ...

evolution of co-continuous morphology along the screw length in a co-rotating twin-screw extruder and its effect on impact strength of compatibilized pa6/abs blend

an ultra-glide twin screw extruder is employed to allow the quick and easy removal of the screws from the fixed processing section within few seconds, probing the current degree of the melting state, the dispersive anddistributive processing steps and finally the level of morphology development along extruder screws. for morphological studies the molten samples, collected from different points ...

determination of maximal singularity free zones in the workspace of parallel manipulator

due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
