Abstract

The present study focuses on understanding the effect of different flow conditions on the phenomenon of vortex formation in steel making tundish. The current study uses the physical water models supported with mathematical models. The aim of the study is to gain fundamental knowledge about effect of individual flow parameters on vortex generation phenomenon. The results indicate that flow turbulence is the most governing factor for vortex initiation. Outflow rate from steel making tundish, however, affects vortexing phenomenon in more prominent way as compared to inflow to the same steel making tundish. Allowing flow stagnation also helps in delaying the start of vortex phenomenon. This overall study thus is helpful for tundish design optimization or usage of turbulence suppressing flow modifiers for improvising process yield.
