Special Issue Information

Dear Colleagues,

Because of continuous efforts to reduce the costs of metal materials production, increasing energy efficiency has become a priority task in this industry. In successful metal production plants, careful energy managing for more and more sustainable metal materials making friendly to the environment is intensively promoted. According to European standards, governments are obliged to increase energy efficiency and minimize CO2 emissions and environmental printouts. It was estimated that in the next 10 years it would be necessary to invest several billion Euros for at least a 20% reduction of CO2 emissions. The only way to realize those targets is to modernize metal production processes, equipment, and infrastructure. The most innovative approach to the modernization of plants is the introduction of cloud technologies into metal production processes. According to paradigm 4.0, digital technologies combined with artificial intelligence have the potential to transform metal production processes to a new more efficient level. Another approach to realizing these targets is to introduce advanced process optimizations regarding productivity, product quality, and cost reductions. To reduce the expensive experimental trials used to evaluate the impact of different optimization strategies, advanced process modeling is needed. Modeling and simulations serve us as an invaluable source of information for conducting process analysis and as an alternative to expensive, dangerous, and time-consuming experimental trials.

This Special Issue of Metals will cover recent advances in the modeling and optimization of different sub-processes in metal materials production from casting, rolling, heat treating, product delivery, quality assurance, and machinability assurance, while considering the most recent experimentally obtained process data.

Numerical modeling is the approach used most often for studying and optimizing the molten steel flow in a continuous casting mold. The selection of the physical model might very much influence such studies. Hence, it is paramount to choose a proper model. In this work, the numerical results of four turbulence models are compared to the experimental results of the water model of continuous casting of steel billets using a single SEN port in a downward vertical orientation. Experimental results were obtained with a 2D PIV (Particle Image Velocimetry) system with measurements taken at various cut planes. Only hydrodynamic effects without solidification are considered. The turbulence is modeled using the RANS (Realizable k-ε, SST k-ω), hybrid RANS/Scale Resolved (SAS), and Scale Resolved approach (LES). The models are numerically solved by the finite volume method, with volume of fluid treatment at the free interface. The geometry, boundary conditions, and material properties were entirely consistent with those of the water model experimental study. Thus, the study allowed a detailed comparison and validation of the turbulence models used. The numerical predictions are compared to experimental data using contours of velocity and velocity plots. The agreement is assessed by comparing the lateral dispersion of the liquid jet in a streamwise direction for the core flow and the secondary flow behavior where recirculation zones form. The comparison of the simulations shows that while all four models capture general flow features (e.g., mean velocities in the temporal and spatial domain), only the LES model predicts finer turbulent structures and captures temporal flow fluctuations to the extent observed in the experiment, while SAS bridges the gap between RANS and LES.
