On the minimum fluidization velocity in 2D fluidized beds [PDF]
Powder Technology, 2011 In the present study, a new correlation for the determination of the minimum fluidization velocity in 2D fluidized beds was developed. The proposed correlation was based on the experimental results obtained in 2D fluidized beds with different particle sizes, bed thicknesses and bed heights.

Improving Nanosilica Fluidization by Premixing with Geldart A and B Particles: A Detailed Region-Wise Study [PDF]
NanomaterialsUltrafine nanosilica exhibits a strong tendency to form agglomerates, with sizes often several orders of magnitude larger than the primary particles. This agglomeration severely impairs its effectiveness in fluidization and other applications requiring ...

Predicting the Minimum Fluidization Velocity of Multicomponent Systems.
Journal of Chemical Engineering of Japan, 1994 An expression is suggested to appropriately estimate the minimum fluidization velocity of either a perfectly mixed or a completely segregated multicomponent system. Based on experimental data from the literature and our own work it is found that agreement between predictions and experimental results is reasonably good in the context of the inherent ...

Hydrodynamic Properties Investigation of Ebullated Bed Reactor Using Non-Newtonian Liquid [PDF]
Engineering and Technology Journal, 2022 The importance of using EBR has been renewed recently due to the sharp increase in heavy feedstocks sent to refineries and the hydrocracking process. Most of these feedstocks have a non-Newtonian behavior.
