| 2 | Measuring turbulence in a circulating fluidized bed using PIV techniques显示文摘This study utilized the particle image velocimetry (PIV) technique, non-invasively near the wall, in the developing region, for the measurements of laminar and turbulent properties during circulation of Geldart B type particles in the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) riser. A novel method was used to measure axial and radial laminar and turbulent solids dispersion coefficients using autocorrelation technique. The instantaneous and hydrodynamic velocities for the solid phase were measured simultaneously in the axial and radial directions using a CCD camera, with the help of a colored rotating transparency. The measured properties, such as laminar and Reynolds stresses, laminar and turbulent granular tempera- tures, laminar and turbulent dispersion coefficients and energy spectra exhibited anisotropy. The mixing in the riser was on the level of clusters. The total granular temperatures were in reasonable agreement with the literature values. However, the axial and radial solids dispersion coefficients measured near the wall were slightly lower than the radially averaged values in the literature. | Mayank Kashyap Benjapon Chalermsinsuwan Dimitri Gidaspow | 2011 | Particuology2011，9，6： | 5 |
| 3 | Compact fluidized bed sorber for CO_2 capture显示文摘Multiphase CFD is used to design a compact fluidized bed sorber for CO2 removal from flue gases using sodium or potassium carbonate pellets.The sorber sizes are much smaller than commercial amine absorbers and smaller than other proposed dry adsorbers.The size reduction is due to the elimination of dilute regions that cause bypassing.With proper solids feeding we eliminated the usual core-annular regime found in circulating fluidized beds. | Parinya Khongprom Dimitri Gidaspow | 2010 | Particuology2010，8，6： | 2 |

| 18 | Carbon dioxide desorption behavior of potassium carbonate supported on gamma-alumina solid sorbent in wet fluidized bed under steam atmosphere显示文摘Since the carbon dioxide(CO_(2))capture using solid sorbent is a reversible reaction,the solid sorbent can be regenerated by the desorption process.Therefore,the desorption process is one of the key important processes for the CO_(2)capture system.Traditionally,most of the literature studies focus on the desorption of solid sorbent under an N_(2)atmosphere.However,the desorption process of the solid sorbent is inappropriate in the real system because the system will need another process to separate CO_(2)and nitrogen(N_(2))after the desorption process.This study focused on the CO_(2)desorption of potassium carbonate supported on gamma-alumina(K2CO3/γ-Al_(2)O_(3))in a wet fluidized bed under a steam atmosphere by using the multiphase computational fluid dynamics(CFD)simulation.The effects of water thickness and dry restitution coefficient on CO_(2)desorption rate were investigated to provide a realistic particle collision behavior and to explore their effects on CO_(2)desorption phenomena.Moreover,the effect of steam velocity on the hydrodynamic behaviors of fluidization which on CO_(2)desorption rate was studied.The simulated results demonstrated that all the parameters,water thickness,dry restitution coefficient,and steam velocity had significantly affected system hydrodynamics and CO_(2)desorption rate in the wet fluidization desorption process.Furthermore,the effect of desorption temperature on CO_(2)desorption rate was evaluated for finding the appropriate temperature for CO_(2)desorption process of K2CO3/γ-Al_(2)O_(3).The results showed that the appropriate desorption temperature for CO_(2)desorption under steam atmosphere was the temperature over 150℃. | Sasitron Angkanawisan Dimitri Gidaspow Pornpote Piumsomboon Benjapon Chalermsinsuwan | 2023 | Particuology2023，，10： | 0 |
