This study investigates how the confetti behave, deform and interact with each other, the flow and the pipe walls, to get a better understanding of how and why these jams occur.įluid structure interaction (FSI), which is a class of multi-physics and deals with the inter- action between fluid flow and deformable structures, is employed to model the confetti in a pipe flow. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flowĭepartment of Energy Sciences Abstract In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps.
