New and more complex casting technologies are growing, and foundries are using innovative methods to reduce cost and energy consumption and improve their product qualities. Numerical techniques, as tools to design and examine the process improvements, are also evolving continuously to embrace modelling of more dynamic systems for industrial applications. This paper will present a fresh approach towards the numerical simulation of dynamic processes using an evolving and dynamic mesh technique. While the conventional numerical techniques have been employed for these dynamic processes using a fixed domain approach, the more realistic evolving approach is used herein to match the complex material processes in new foundries. The underpinning of this new dynamic approach is highlighted by an evolving simulation environment where multiple mesh entities are appended to the existing numerical domain at timesteps. Furthermore, the change of the boundary and energy sources within casting process simulations have rationally been presented and its profound effects on the computational time and resources have been examined. The discretization and solver computational features of the technique are presented and the evolution of the casting domain (including its material and energy contents) during the process is described for semi-continuous casting process applications.

新铸造铸造的数值模拟:动态过程模拟

新的和更复杂的铸造技术正在发展,铸造厂正在使用创新的方法来降低成本和能耗,并提高其产品质量。数值技术作为设计和检查过程改进的工具,也在不断发展,以涵盖针对工业应用的更多动态系统的建模。本文将提出一种使用演化和动态网格技术进行动态过程数值模拟的新方法。尽管已使用固定域方法将常规数值技术用于这些动态过程,但本文使用了更现实的演变方法来匹配新铸造厂中的复杂材料过程。不断发展的仿真环境突显了这种新的动态方法的基础,在该仿真环境中,多个网格实体在时间步长上附加到了现有的数值域上。此外,合理地介绍了铸造过程模拟中边界和能源的变化,并考察了其对计算时间和资源的深刻影响。介绍了该技术的离散化和求解器计算特征,并描述了半连续铸造工艺应用过程中铸造域(包括其材料和能量含量)的演变。合理地提出了铸造过程模拟中边界和能源的变化,并考察了其对计算时间和资源的深刻影响。介绍了该技术的离散化和求解器计算特征,并描述了半连续铸造工艺应用过程中铸造域(包括其材料和能量含量)的演变。合理地提出了铸造过程模拟中边界和能源的变化,并考察了其对计算时间和资源的深刻影响。介绍了该技术的离散化和求解器计算特征,并描述了半连续铸造工艺应用过程中铸造域(包括其材料和能量含量)的演变。
