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.
