The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. During the solidification of a casting in a mould, the heat-transfer between the casting and the mould plays a vital role. This paper attempts to study ...

Abstract The whole process of concrete slump experiment was simulated with Particle Flow Code 3 Dimensions (PFC3D) software based on discrete element simulation. simulation results are in good agreement the macroscopic obtained from field experiments, indicating that use PFC for had feasibility have a observation speed and direction particles slump.

This paper stablishes the model of the integrated batch planning process, and proposes an improved algorithm for this problem. The simulation results of a computerized scheduling system are given to prove the fitness of the model. The steel making casting production process scheduling problem is very difficult to get a good performance solution in practice. The scheduling of steelmaking casting...

Continuous casting is the central process phase with strong influence on the final quality of the steel products. Several different models for continuous casting have been developed at the Laboratory of Metallurgy at Helsinki University of Technology (TKK) concerning e.g. fluid flow, heat transfer, thermodynamic equilibria and statistical approaches. In this paper the inhouse solidification mod...

Optogenetics is a powerful tool for controlling biological functions using light. Optical fibers have been extensively utilized in optical stimulation devices optogenetics. However, the use of results small photo-stimulation region. In this study, micro-LED array were developed to achieve large-area brain large animal, such as macaque monkeys. Planar and linear designed fabricated photo-stimula...

a full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (sen) was constructed. on the basis of the dimensionless reynolds and froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. in order to determine the optimum ope...

In continuous casting of steel, plant observations have found that many serious quality problems are directly associated with the flow pattern in the mold. Previous studies have generated understanding mainly through numerical simulations using timeaveraged turbulence models. However, many problems are intermittent and the essential transient nature of the flow may be important to their formati...

Nowadays acoustic emission (AE) testing based on the Kaiser Effect (KE) is increasingly used to estimate the in-situ stress in laboratories. In this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3D code called the particle flow code (PFC) based upon the distinct element method. T...
