A new technique allows for the detection of particle-particle collisions in liquid-solid and gas-liquid-solid fluidized beds from perturbations in the diffusion current of tethered electrodes. A tethered particle, near its anchorage point, can give a good estimate of the collision frequency of a fre
## Abstract This paper illustrates the interrelation between bubbles, solids movement, and gas backmixing in large fluidized beds by presenting experimental data obtained with a 1.22 m square bed. The results demonstrate a close relationship between gas backmixing, solids movement, and bubble coale
