DESCRIPTION:Speakers: Quinn Reynolds (Mintek)\nDuring the pyrometallurgica
 l production of industrial commodities such as ferromanganese and ferrochr
 omium in electric smelting furnaces\, immiscible molten slag and metal pha
 ses are tapped from the unit at regular intervals. This process involves o
 pening a dedicated channel in the furnace sidewall (the tap-hole) and allo
 wing the contents of the vessel to drain through it. After exiting the tap
 -hole\, the stream of molten material is directed along open launder chann
 els and empties into one or more storage ladles. During this process inter
 mixing of slag and metal phases often occurs\, and if not carefully manage
 d\, can result in significant metal being lost to the waste slag by entrai
 nment. \n\nIn this presentation we show the results of a computational flu
 id dynamics study of the multiphase free surface fluid flow in tapping lad
 les\, and examine how the application of high-performance computing has gr
 eatly expanded our ability to explore the unusual and challenging paramete
 r spaces of problems in pyrometallurgy. Access to facilities such as CHPC 
 allows us to build deeper intuition and fundamental understanding of the c
 omplex fluid flow phenomena occurring during ladle tapping\, and is able t
 o guide us to practical engineering solutions for mitigating losses due to
  phase mixing.\n\nhttps://events.chpc.ac.za/event/98/contributions/1519/
