Summary: This study investigated the complex transport phenomena during laser cladding using a three-phase Eulerian volume averaging approach. The results showed that two distinct vortexes, driven by Marangoni force, significantly influenced the final distribution of compositions in the cladding layer.

Summary: To address the data limitation problem in few-shot learning, a generation-based Transductive Distribution Optimization (TDO) method is proposed. It captures the distributions of few-shot classes using a small number of labeled samples and high-confident unlabeled samples, and generates sufficient samples to augment the labeled inputs.

Summary: The study investigates the effects of using in-mold electromagnetic stirrer in continuous casting mold through a multiphase model. It is found that moving the stirrer away from the interface reduces the intensity and size of the recirculation loop, while the tangential velocity increases. The stirring generated by the electromagnetic stirrer decreases temperature and increases uniformity in liquid fraction, facilitating inclusion removal from the mold.

Summary: Tolerance intervals are designed to contain a certain percentage of a population distribution, but often fail to achieve the desired coverage rates. The choice of tolerance interval method should be based on the specific conditions of the study to ensure proper coverage.

Summary: The temperature dependence on the deoxidation reactions during cooling of molten steel and the solute microsegregation during solidification significantly affect the composition of oxide inclusions. The microsegregation behavior of solute elements plays an important role in the formation of inclusions, which is of great importance in the production of high-quality steels.

Summary: In this paper, an accurate interface-capturing lattice Boltzmann method is proposed based on the modified Allen-Cahn equation for modeling an immiscible multiphase flow system. The proposed method is built on the relation between the signed-distance function and the order parameter, maintaining the mass-conserved characteristic. By carefully incorporating a suitable forcing term, the target equation can be correctly recovered. Simulation results for various interface-tracking problems demonstrate that the proposed model is more numerically accurate, particularly at a small interface-thickness scale, compared to existing lattice Boltzmann models for the conservative Allen-Cahn equation.

Summary: The study found that under a temperature gradient, the growth rate of second-phase particles in binary model alloys is faster, and the steady-state particle size distribution depends on the magnitude of the temperature gradient. Additionally, particles migrate from low temperature regions to high temperature regions under a non-uniform temperature field.

Summary: The study demonstrates that a static magnetic field can alter the convective transport of heat and mass during the laser cladding process, resulting in uneven distribution of iron concentration due to the induced Lorentz force inhibiting melt flow.

Summary: The asymptotic analysis of multi-phase-field models is often not rigorously performed, and the justification for certain model assumptions is usually heuristic. The transition from an initial filling to a state characterized by separated bulk phases is rarely addressed, and there is a lack of detailed numerical studies on the predicted asymptotic laws.

Summary: This study developed a calculation model for crack initiation and propagation of continuous casting round billets based on the Element-Free Galerkin method. The diffraction criterion and direct displacement method were used to study crack parameters, showing that crack propagation mainly occurs around 110 to 300 mm below the meniscus of the billet.

Summary: The effect of electric current on the refinement of pure aluminum during solidification was investigated in this study. It was found that electric current can significantly alter the grain morphology and reduce grain size. The grain refinement is influenced by electrical conditions such as the intensity and duration of applied electric current, but under extreme conditions, the refining effect may disappear.
