Videos - Fluidisation of calcite-pellets 0.8-0.9mm and 1.4-1.7 mm in water for various flow rates

52 videos calcite grains fluidised in water in an experimental setup using a Canon LEGRIA HF G25 camera. CaCO₃ calcite pellets (1.4-1.7mm) and (0.8-0.9mm) in a D=57mm PVC transparent cylindrical column with water at 18 °C for various linear flow rates (flow from left to right). An advanced experimental study at the pilot plant at Waternet Amsterdam.This research is part of the project “Hydraulic modelling of liquid-solid fluidisation in drinking water treatment processes” carried out by Waternet, Delft University of Technology. Financial support came from Waternet Drinking Water Production Department.<br>本数据集包含52段视频，记录了实验装置中水流流化的方解石颗粒，实验采用佳能LEGRIA HF G25摄像机拍摄。实验使用粒径分别为1.4~1.7mm与0.8~0.9mm的碳酸钙（CaCO₃）方解石颗粒，在内径D=57mm的聚氯乙烯（PVC）透明圆柱柱体内开展，柱内水温为18℃，并设置了多种线性流速工况，水流方向为从左至右。本实验为阿姆斯特丹水务公司（Waternet）中试基地开展的前沿实验研究。本研究是Waternet与代尔夫特理工大学联合实施的项目“Hydraulic modelling of liquid-solid fluidisation in drinking water treatment processes”的组成部分。本研究得到了Waternet饮用水生产部门的经费支持。
