Abstract
The fluid flow patterns generated during the course of tapping operations from Basic Oxygen Furnaces have been analyzed using two mathematical models of the filling process. The present work is mainly concerned with the application of the κ — ∈ turbulent flow model to describe recirculatory flow in filling ladles. Predicted velocity fields were quite similar to those based on the laminar flow model and both models provided predictions which checked reasonably closely with experimental values using a one tenth scale model. Based on the full scale predictions, it is suggested that the magnitude of flow velocities are technologically significant in terms of their effect on ferro-alloy immersion times.
