Magnetic resonance velocimetry of particle hydrodynamics in a three-dimensional draft tube spout-fluid bed

This dataset augments the article: "Magnetic resonance velocimetry of particle hydrodynamics in a three-dimensional draft tube spout-fluid bed" published in Chemical Engineering Journal (https://doi.org/10.1016/j.cej.2024.149678). 

This dataset consist of 

Magnetic resonance velocimetry data of a vertical cross-section through a draft tube spout-fluid bed at various operational settings. The data is saved as a MATLAB ".mat" file (Velocity.mat). This file contains a struct that relates the velocity fields in the annular region (ann_vx and ann_vy) and the tube region (tube_vx and tube_vy) to the respective settings of the experiments.  The fields of the struct are as follows

Qf: Gas flow rate of the background fluidization in liters per minute at norm conditions

Qs: Gas flow rate of the spout flow in liters per minute at norm conditions

L: Length of the draft tube in mm

Hg: Gap height of the draft tube in mm

D: Diameter of the draft tube in mm

Hb: Bed height of the particle bed in mm

ann_vx: Horizontal velocity of the particles in the annular region in cm/s

ann_vy: Vertical velocity of the particles in the annular region in cm/s

tube_vx: Horizontal velocity of the particles in the tube region in cm/s

tube_vy: Vertical velocity of the particles in the tube region in cm/s
