Secondary solid phase mixing in a circulating fluidized bed - part 1: base case

Dataset consisting of transient Eulerian multiphase flow and mixing of a secondary, minor particle phase in a laboratory-scale circulating fluidized bed.
Data generation and related parameters are described in Nikku et al. (https://doi.org/10.1016/j.ces.2023.118503)

The data files are in different folders, depending on the material properties (cases correspond to those mentioned in the article, Table 2.). The case labeling is also described in the description file provided with the full dataset. The ASCII data files have the format of Ansys Fluent interpolate files (.ip) and they are given with 50 ms intervals (labeled in the filename) for the whole riser and the data files contain:
x-coordinate, y-coordinate (vertical direction), z-coordinate, pressure, mp-1 (gas phase), mp-2 (bed material), mp-3 (secondary solid phase), x-velocity-1 (gas), y-velocity-1, z-velocity-1, x-velocity-2 (bed material), y-velocity-2, z-velocity-2, x-velocity-3 (secondary solid phase), y-velocity-3, z-velocity-3.
This first part of the data set contains the 22 transient base cases as well as 10 case and 22 case averaged versions.

本数据集包含实验室规模循环流化床（circulating fluidized bed）内的瞬态欧拉多相流（transient Eulerian multiphase flow）与次要微量颗粒相的混合过程数据。数据生成方法及相关参数详见Nikku等人的研究（https://doi.org/10.1016/j.ces.2023.118503）。

数据文件按物料属性分类存储于不同文件夹，各工况与论文表2中提及的工况一一对应，工况命名规则详见完整数据集附带的说明文档。ASCII格式数据文件采用Ansys Fluent插值文件格式（.ip），以50ms为间隔采集整个提升管的流场数据（文件名中标注了采集间隔），数据字段包含：x坐标、y坐标（垂直方向）、z坐标、压强、mp-1（气相）、mp-2（床料）、mp-3（次要固相）、x方向速度1（气相）、y方向速度1、z方向速度1、x方向速度2（床料）、y方向速度2、z方向速度2、x方向速度3（次要固相）、y方向速度3、z方向速度3。

本数据集第一部分包含22个瞬态基础工况，以及10组工况平均与22组工况平均后的数据集。
