List of Symbols

Aes

exposed spout area measured at the slag-air interface

As

spout area measured at the slag-metal interface

des

diameter of the exposed spout measured at the slagair interface

ds

diameter of the spout measured at the slag-metal interface

Fr

ladle Froude number

fnos

fraction of the experimental observations where a plume eye was discemible

g

acceleration due to gravity

H

depth of upper phase fluid (slag) in the ladle

h
