Non-isothermal Simulation of the Flow in Co-rotating and Counter-rotating Twin-screw Extruders Using Mesh Partitioing Technique
نویسنده
چکیده
A new algorithm for simulation of non-isothermal flow in a twin-screw extruder is introduced. In the new algorithm, the finite element mesh of tetrahedral elements is created in the complete barrel including the space occupied by the screws. By partitioning the tetrahedral elements which are intersected by the screw surfaces into two tetrahedral, pyramidal or prismatic finite elements, the new algorithm allows the flow simulation in twinscrew extruder without regenerating the finite element mesh as the two screws rotate.

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 ...

A Pareto Local Search (PLS) algorithm was developed and applied to the screw configuration of co-rotating twin-screw extruders. This problem can be seen as a sequencing problem where a set of different screw elements are to be sequentially positioned along the screw in order to maximize the extruder performance. The results obtained were compared with previous results obtained with a Multi-Obje...

We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz). The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...
متن کاملApplication of Pareto Local Search and Multi-Objective Ant Colony Algorithms to the Optimization of Co-Rotating Twin Screw Extruders
Co-rotating twin screw extruders are extensively used in the polymer compounding industry mainly due to their good mixing capacity. Given its modular construction, this type of machines can easily be adapted to work with different polymeric systems, e.g., polymer blends, nanocomposites or highly filled polymers. Nevertheless, the performance of these machines is strongly dependent on the screw ...

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 ...
