TL;DR: In this paper, a dual flow divider is configured to separate the melt stream received from the extruder at a central entry into two flow channels, the respective channels being formed as nearly to identical (mirror image) as possible.
Abstract: The present invention provides a dual flow divider for use on an extruder The flow divider is configured to separate the melt stream received from the extruder at a central entry into two flow channels, the respective channels being formed as nearly to identical (mirror image) as is practically possible The relative flow in the respective channels can be varied by rotating a diverter valve that extends to a position adjacent the central entry of the flow divider, ie, where the flow begins to divide The flow channels and control end of the diverter valve are specially configured to avoid any shape or surface conditions that would impose heat-generating restrictions to material flow, and/or allow areas of stagnation in the flow stream More specifically, the flow channels are machined to provide smooth, streamlined transitions at all points along the flow path The surfaces of the flow channels which intersect with the diverter valve do so at a sharp edge; this geometry blends the surfaces of the channels and valve while also serving as a "wiper" when the valve is rotated

TL;DR: A dynamic model has been developed for reused and recycled packaging material flows that allows a rigorous description of the flows and stocks during the transition to new targets imposed by legislation, product demand variations or even by variations in consumer discard behaviour.

TL;DR: In this paper , a thermal-fluid coupling model based on computational fluid dynamics is established, and related experiments are designed to verify the difference in the temperature distribution and the characteristics of the material flow.
Abstract: Friction stir welding (FSW) involves complex interactions between thermal, mechanical and geometric effects. The thermal process and material flow in the welding process significantly influence the microstructure evolution and the final mechanical properties of the joint. This paper aims to determine the influence of the thermal process and material flow on welding defects during high-speed FSW of an aluminum alloy. A thermal-fluid coupling model based on computational fluid dynamics is established, and related experiments are designed to verify the difference in the temperature distribution and the characteristics of the material flow. The results show that the calculation results can accurately describe the quasi-steady state heat-flux coupling state during FSW. In high-speed welding, the material produces a considerable strain rate. The contact friction stress of the tool decreases as the temperature of the material increases. The dynamic recrystallization phenomenon is more evident on the advancing side, but there are tiny void defects on the advancing side.

TL;DR: The application of discrete event simulation to study continuous material flow is described to determine the required logistics operations to allow continuous operations of a chemical manufacturing plant.
Abstract: This paper describes the application of discrete event simulation to study continuous material flow. Logistics is an integrated part of most manufacturing companies. The purpose of this study is to determine the required logistics operations to allow continuous operations of a chemical manufacturing plant. The application has been used to provide critical decision support.
