抄録	The application of the swirling flow by funnel to the steel refining process has been expected. In order to generate the swirling flow effectively and to maintain stably, it is necessary to examine the optimum conditions from various viewpoints, such as the shape of the funnel. In addition, it is necessary to clarify the effect of the wettability between the solid surface and the liquid on the swirling flow. Using mercury or water, the swirling flow in the funnel has been observed, and the effect of the funnel angle and the wettability on the swirling flow has been investigated. The swirling flow by funnel is formed stably when the funnel angle against the horizontal surface is larger than 60° in spite of the wettability of the funnel with the liquid. When the funnel angle becomes smaller, such as 30°, the swirling flow is affected by the wettability of the funnel. When the wettability between the funnel and the liquid is poor, the stable swirling flow cannot be obtained because of the slip of the liquid on the inner-surface of the funnel. A model calculation for molten iron has also been conducted on the effect of the wettability on the swirling flow. In regard to the liquid flow of the vertical direction, the liquid flows downward at the surface side of the liquid and upward at the vicinity of the funnel. When the wettability of the inner surface of the funnel with the liquid is poor, the liquid flows more intensely. This may be one of the causes that the swirling flow is difficult to be stabilized when the wettability is poor.

DCTERMS.abstract	The application of the swirling flow by funnel to the steel refining process has been expected. In order to generate the swirling flow effectively and to maintain stably, it is necessary to examine the optimum conditions from various viewpoints, such as the shape of the funnel. In addition, it is necessary to clarify the effect of the wettability between the solid surface and the liquid on the swirling flow. Using mercury or water, the swirling flow in the funnel has been observed, and the effect of the funnel angle and the wettability on the swirling flow has been investigated. The swirling flow by funnel is formed stably when the funnel angle against the horizontal surface is larger than 60° in spite of the wettability of the funnel with the liquid. When the funnel angle becomes smaller, such as 30°, the swirling flow is affected by the wettability of the funnel. When the wettability between the funnel and the liquid is poor, the stable swirling flow cannot be obtained because of the slip of the liquid on the inner-surface of the funnel. A model calculation for molten iron has also been conducted on the effect of the wettability on the swirling flow. In regard to the liquid flow of the vertical direction, the liquid flows downward at the surface side of the liquid and upward at the vicinity of the funnel. When the wettability of the inner surface of the funnel with the liquid is poor, the liquid flows more intensely. This may be one of the causes that the swirling flow is difficult to be stabilized when the wettability is poor.
