铸造工程师越来越多地采用用于模拟铸造过程的数值工具来理解和改进铸造技术。正确模拟填充过程中的金属流动和温度分布是整体数值模拟套件的重要组成部分，该套件包括凝固和残余应力评估。
在这项研究中，我们开发了一个二维有限元模型，研究金属流动和温度场在模具型腔填充。适当选择湍流/层流模型，正确跟踪金属自由表面和评估温度，包括金属-空气-沙子相互作用是模型的一些基本特征。
Numerical tools for simulating the casting process are employed in an increasing manner by foundry engineers in order to understand and improve casting techniques. The correct simulation of metal flow and temperature profiles during filling is an important part of an overall numerical simulation kit which includes solidification and residual stress evaluations.
In this study, we develop a two-dimensional finite element model for studying metal flow and temperature fields during filling of mould cavities. A proper choice of turbulent/laminar model, correct tracking of metal free surface and evaluation of temperature to include metal-air-sand interaction are some of the essential features of the model.
