Experiments were conducted with 6 mm plastic beads (Geldart Group D) in a semi‐circular, gas‐fluidized bed with side jets. Attention was paid to particle characterization and bed measurements, making the resulting dataset ideal for CFD‐DEM validation and uncertainty quantification. The bed was operated slightly above and below the minimum fluidization velocity, with additional fluidization provided by one of two pairs of opposing jets located above the distributor near the flat, front face of the unit. Care is taken to report material properties and bed conditions with either measured distribution functions or uncertainty bounds. High‐speed video imaging and particle tracking velocimetry are used to extract bin‐averaged velocity profiles, which are used to extract jet penetration depths. The time‐averaged mean and standard deviation of the bed pressure drop is also reported. Finally, the lower jets are also inserted into the bed until the opposing jets merge to form a spout‐like pattern. © 2018 American Institute of Chemical Engineers AIChE J, 64: 2351–2363, 2018

代码验证的实验数据：Geldart D组颗粒的半圆形流化床中的水平空气喷射

实验是在带有侧面射流的半圆形气体流化床中，用6毫米塑料珠（Geldart组D）进行的。注意颗粒表征和床层测量，使所得数据集非常适合CFD-DEM验证和不确定性定量。床在最小流化速度的略微上方和下方操作，附加的流化由位于分配器上方，靠近设备的平坦正面的两对相对的喷嘴中的一对提供。小心地报告具有测量分布函数或不确定性界限的材料特性和床况。高速视频成像和粒子跟踪测速仪可用于提取bin平均速度分布图，该分布图可用于提取射流穿透深度。还报告了床压降的时间平均和标准偏差。最后，下部喷嘴也插入床中，直到相对的喷嘴合并成喷口状。©2018美国化学工程师学会AIChE J，64：2351–2363，2018年
