Description
Summary:Splash must often be avoided or minimised in many materials processing operations, but in some cases the process can be designed to control splash for heat and or mass transfer. In all cases careful design is required and CFD modelling can play a critical role in this. Unfortunately, splash is a complex process for which CFD modelling has not been widely applied in the design arena. The phenomenon involves multi-scale issues, with surface properties playing an important role. The paper describes the physics of splash mechanisms, particularly as caused by bubbling through molten metals, and summarises some of the CFD techniques that have been used to simulate such splash. Examples of CFD models developed for modelling splash in ferrous and non-ferrous smelting processes are described.
