The self-wiping co-rotating twin-screw extruder as a polymerization reactor for methacrylates

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 ...

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 ...

Application of Analytical Technique to Resolving the Flow Dynamics in Self-wiping Co-rotating Twin Screw Extruders

In this paper, a method by which the fluid velocity profile and the net flow rate in self-wiping co-rotating twin screw extruders can be estimated without determining the pressure gradient has been proposed. The method involves using analytical technique to determine the fluid velocity in the local zones of the extruder such as the down channel and axial velocity and subsequently, the net flow ...

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 ...
