“…There are many experimental studies of the solid circulation pattern in fluidized beds with a single jet (e.g. Yang, Ettehadieh, & Haldipur, 1986) or of numerical simulations (e.g. Gidaspow & Ettehadleh, 1983;.…”

“…Related experimental technology to study the bubbling bed has been developing along the time. Yang et al studied the bubble characteristics using digital image analysis. The x‐ray analysis was employed to study the single bubbles by Yates et al Mychkovsky et al used laser doppler velocimetry measurement to analyze the gas and particle velocity profiles in fluidized beds.…”

As liquid bridge between particles acts an important role in the particle system, it is of considerable significance to analyze the flow hydrodynamics of wet particles in fluidized beds, which will improve the reactor design and process optimization. Thus, experimental and numerical investigations on wet particles in a bubbling fluidized bed are conducted in current work. On experimental side, particle image velocimetry (PIV) technology is employed with a designed bubbling fluidized bed. The silicone oil is used in this work because it is nonvolatile and transparent. On numerical side, a modified discrete element method (DEM) numerical method is developed by compositing an additional liquid‐bridge module into the traditional soft‐sphere interaction model. Most of the physical parameters are chosen to correspond to the experimental settings. Good agreements of particle velocity are found between the DEM simulation and PIV measurement. The performance of different liquid contents and superficial gas velocities are examined. © 2016 American Institute of Chemical Engineers AIChE J, 62: 1970–1985, 2016

“…The high speed motion capture method is widely used in this type of study, such as the one used by Yang et al [7] who studied bubble characteristics. X-ray analysis was employed to study single bubbles in a jetting fluidized bed near the jets in the work by Yates et al [8] Mychkovsky et al [9,10] used Laser Doppler Velocimetry (LDV) measurements to analyze the gas and particle velocity profiles in jetting fluidized beds.…”
