Mathematical modeling of hydrodynamics of the bubble mode during the bottom blowing of the ladle furnace

The results of a mathematical modeling of size variations of the gas bubble upon its motion to the melt surface during the fire refining of copper in the ladle furnace are presented. The degrees of influence of the temperature field and hydrostatic pressure on these sizes are determined. The essenti...

Zusammenfassung:	The results of a mathematical modeling of size variations of the gas bubble upon its motion to the melt surface during the fire refining of copper in the ladle furnace are presented. The degrees of influence of the temperature field and hydrostatic pressure on these sizes are determined. The essential variation in the bubble volume allows us to conclude the time-dependent character of its motion along the melt height.
