The interplay of flow and solute fields during the solidification of Al-Bi alloy via the X-ray radiography and optical flow approach (processed solute data)

Solidification is directly determined by multi-fields. Visualization of the flow field, the solute content field, as well as the constitutional undercooling field during the solidification of immiscible Al-Bi alloy, was conducted via X-ray radiography and optical flow approach. The related detailed description and analysis as well as the steps to reproduce were referred to in the paper titled “The interplay of flow and solute fields during the solidification of Al-Bi alloy via the X-ray radiography and optical flow approach”.
Here, the solute profile and the optical flow measurements based on the raw radiographs which were recorded during the solidification of immiscible Al-Bi alloy were uploaded, where the unit of the optical flow and solute profile data respectively “m/s” and “× 100 %”. The positive vertical flow velocity (VY) is in the downward direction. The positive horizontal flow velocity (VX) is in the rightward direction. V is the net velocity.

凝固过程直接由多场共同决定。针对互不相溶Al-Bi合金（immiscible Al-Bi alloy）凝固过程中的流场、溶质含量场以及成分过冷场（constitutional undercooling field），研究人员采用X射线照相术（X-ray radiography）与光流法（optical flow approach）开展了可视化工作。相关详细描述、分析内容及复现步骤可参考题为"基于X射线照相术与光流法的Al-Bi合金凝固过程流场与溶质场交互作用"的学术论文。
本数据集上传了基于互不相溶Al-Bi合金凝固过程中采集的原始X射线照相图像所得到的溶质分布数据与光流测量数据，其中光流数据的单位为"m/s"，溶质分布数据的单位为"×100 %"。垂直流速度（VY）的正方向为向下，水平流速度（VX）的正方向为向右，V为合速度。
