| 摘 要： | 采用改进后的ＳＯＬＡ－ＶＯＦ方法处理自由表面，有效地克服了传统的ＳＯＬＡ－ＶＯＦ法中的“施体－受体”法在处理三维自由表面时精度差和时间步和菠的缺点。在自由表面处理上采用了新的压力插值函数，使三维自由表面的处理变得简单明了。用有限差分法建立了铸件三维充型过程流动与传热的耦合计算数值模型，并对大型灌壁铅合金件进行了数值计算。后处理中采用插值技术，直观地显示了充填过程中自由表面的位置和形状。

| Abstract: | The numerical model for 3D fluid flow coupled with heat transfer was established with FDM and the free surfaces were handled by an improved SOLA VOF technique. A pressure interpolation function was adopted as the free surface boundary condition. The example of large thin wall Al alloy casting was calculated with this model. In the post processing, the location and shape of free surfaces during mold filling were displayed visually with a linear interpolation method. |
