The series of experiments have been performed on a 2.5-inch cylindrical bed made of acrylic with full optical access and multiple pressure ports at various heights of the bed. The material of interest includes in the investigation include Geldart type D cylindrical hardwood pellets, Geldart type D spherical LDPE, and Geldart type B sand particles. The wood particles have a diameter of around 6.6 mm and a length of 13.2 mm, corresponding to an aspect ratio of 1:2. The spherical LDPE particles and the sand particles have a Sauter Mean Diameter of 3.75 mm, and 0.5 mm, respectively. The experiment series involved the fluidization of the above-mentioned single particle type, as well as the fluidization of binary and ternary mixtures with varying superficial velocities.
