Abstract
Efficient agitation of molten steel and slag is requested in the steelmaking industry. The conventional agitation methods are Ar gas injection and electromagnetic stirring. These methods are very expensive, and accordingly, we have proposed an alternative, cheap and effective mixing method using a swirl motion. This method does not need any driving devices in the reactor. In this study, we place a lowdensity liquid or low-density particles on a cylindrical water bath and investigate the effect of the upper layer on the amplitude of swirling liquid jet.
