Fundamentals of Scale up Procedures to Model Liquid Steel-Argon Flows in Slab Molds
Modeling two-phase flows using a wetting liquid such as water modeling in downscaled models can lead to unreliable results as much as using non-wetting systems in downscaled sizes.As the size of the model gets smaller the surface tension forces take preponderance over the inertial ones.These conditions inevitably will lead to unusual laminar flows and high population of bubbles in the lower part of the mold which make unrealistic any modeling work.These effects are particularly intensive using non-wetting liquids.Therefore,the best approach to model these types of flows is using non-wetting liquids in full scale models,although,this would be extremely expensive.This leaves only water as the most available and less expensive liquid to model two-phase flows in the mold.This hypothesis is tested in the present contribution through theoretical considerations of the turbulence theory,dimensional analysis and multiphase flow simulations.
