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

凝固过程直接由多场共同决定。针对不混溶Al-Bi合金（immiscible Al-Bi alloy）的凝固过程，本研究通过X射线照相术（X-ray radiography）与光流法（optical flow approach）实现了其流场、溶质含量场以及成分过冷（constitutional undercooling）场的可视化。相关详细描述、分析内容及复现步骤可参见题为《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相互作用》的学术论文。
本数据集上传了基于不混溶Al-Bi合金凝固过程中采集的原始X射线底片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（VY）的正方向为向下，水平流速（VX）的正方向为向右。
