Experimental study of heating and cooling of a shallow packed bed suspected to air temperatures between 300 and 773 K

The presented dataset comprises nine experiments conducted on a shallow packed bed with an aspect ratio of 0.5, evaluated under varying inflow configurations and fluid flow rates (see folders 1 to 9). For each experiment, the packed bed was heated from ambient temperature to approximately 773 K using hot air, with subsequent cooling with air at nearly ambient temperature. Temperature was measured using thermocouples strategically positioned below, within, and above the packed bed at various radial and axial locations. Pressure transmitters recorded the pressure drop across the packed bed, while an infrared camera monitored the surface temperature of the bed during the cooling phase, adding value to point wise measurement data of thermocouples. A particle size analysis was performed using the software ImageJ, with the results included in the "0_GeneralInformation" folder, which also contains details about the infrared measurements, sensor description etc. Additionally, the "10_AllPlots" folder provides an overview of the data from each individual measurement device, such as thermocouples and mass flow sensors, offering a quick summary of sensor outputs.

The accompanying article, submitted in Data in Brief, shows structured data examples and detailed analyses, including examples of infrared photography as well as a comprehensive description of the experimental conditions and test setup.

本数据集包含9组实验，均在长径比为0.5的浅填充床（shallow packed bed）上开展，实验在不同进气配置与流体流速条件下进行，相关数据存储于文件夹1至9中。每组实验中，填充床均以热空气从环境温度加热至约773 K，随后采用接近环境温度的空气完成冷却流程。温度通过热电偶（thermocouples）测量，热电偶被优化布置在填充床下方、内部及上方的多个径向与轴向位置处。压力变送器（pressure transmitters）记录填充床的压降数据；冷却阶段通过红外相机（infrared camera）监测填充床表面温度，为热电偶的单点测量数据提供补充支撑。本研究使用ImageJ软件开展粒子尺寸分析（particle size analysis），分析结果存储于"0_GeneralInformation"文件夹中，该文件夹还包含红外测量详情、传感器说明等内容。此外，"10_AllPlots"文件夹汇总了各测量设备（如热电偶与质量流量传感器（mass flow sensors））的原始数据，可快速概览各类传感器的输出结果。
