| Abstract Scope |
In pyrometallurgical smelting dispersed multiphase flows can occur due to phase mixing between immiscible molten process materials such as slag and alloy, or decoupling of gases from one of the molten phases. The latter problem can result in slag foaming, which occurs when gas bubbles are unable to escape from the viscous slag phase rapidly enough and a low-density foam layer builds up at the surface of the slag pool. This paper will present the evaluation and application of the dynamic multi-marker (DMM) method, a novel meso-scale computational fluid dynamics algorithm for efficient modelling of dispersed phase systems, for slag foaming problems. Foaming behaviour and gas-liquid decoupling will be studied using numerical simulations of test systems, and the results will be compared to established empirical relationships. The value of DMM both as a direct simulation method and for supplementation of experimental data will be assessed and discussed. |
