A finite volume numerical model was developed to determine the fluid flow patterns and investigate the transient behaviour of the slag/steel (oil/water) interface using a water model configuration. This model includes a Lagrangian representation of argon bubble tracks and their influence on the flowfield (due to buoyancy) and on surface behaviour. In the process of validation between the multi-phase model and the LDA experimental measurements several explanations are provided for the different observed phenomena and their influence on the Continuous Casting of steel. As a next aim in the project, the heat transfer between slag and steel in an industrial configuration is studied. These multi-phase interactions involve the melting of the flux powder and the formation of the slag layer.
