Transient Eulerian simulations of multiphase flow inside a laboratory-scale circulating fluidized bed (CFB) riser were performed with air, bed material, and a secondary solid phase to evaluate the mixing of the secondary solid phase. This simulation data can be applied in model development or for computing terms that are commonly used when modeling mixing with simplified models (pseudo-steady state, non-convective models, etc.). The data was produced with transient Eulerian modeling using Ansys Fluent 19.2. The simulations were done with one fluidization velocity and bed material, while the density, particle size, and inlet velocity of the secondary solid phase was varied and 10 simulations per each secondary solid phase case were simulated for 1 s, each simulation having different starting conditions (flow state of the air and bed material) inside the riser. These 10 cases were then averaged to provide an average mixing profile for each secondary solid phase. Both the averaged and un-average data are included. The details of the modeling, averaging, geometry, materials, and cases are described in the open-access publication by Nikku et al. (Chem. Eng. Sci. 269, 118503).
使用空气、床料和第二固相在实验室规模的循环流化床（CFB）提升管内进行多相流的瞬态欧拉模拟，以评估第二固相的混合情况。该模拟数据可应用于模型开发或用于计算与简化模型（伪稳态、非对流模型等）混合建模时常用的项。这些数据是使用Ansys Fluent 19.2通过瞬态欧拉建模生成的。模拟在一个流化速度和床料条件下进行，同时改变第二固相的密度、粒径和入口速度，每个第二固相工况模拟10次，每次模拟1秒，每次模拟在提升管内具有不同的起始条件（空气和床料的流动状态）。然后将这10种工况进行平均，以提供每个第二固相的平均混合分布。包含了平均数据和未平均数据。建模、平均、几何形状、材料和工况的详细信息在Nikku等人的开放获取出版物（《化学工程科学》269, 118503）中有描述。
