Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
11 high speed camera videos of liquid-solid fluidisation experiments in a university laboratory. You see a 57 mm PVC column where tap water is pumped in an upward direction causing particles to elevate into a fluidised state. Particles are (calcium carbonate) calcite grains obtained from a full-scale drinking water softening reactor. The reason to show this video is to demonstrate that homogenous flow regime not always occurs whilst this is often assumed regarding l-s fluidisation systems. The viewer can observe open voids of water between the particles and water which choses a path of least resistance through the particle bed. Besides laminar-turbulent regime also homogenous-heterogeneous distinction is relevant. The videos can be used for analysis purposes e.g. ImageJ particle tracking.
