Mass transfer and concentration boundary layer in a particulate fluidized bed
(Elsevier Science Bv, Amsterdam, 2016)
The aim of this study was to analyze the concentration boundary layer for a comprehensive description of the mass transfer in systems with fluidized particles. Mass transfer from the wall of the column to the fluid in the ...
Solid circulation rate and particle collisions in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier Science Bv, Amsterdam, 2014)
The equations for the overall particle circulation rate and the frequency of particle-particle collisions in the quasi two-dimenional water-fluidized bed were proposed. The equations were based on the experimental results ...
Hydrodynamic modeling of downward gas-solid flow. Part II: Co-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward co-current gas-solid flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. The ...
Optimal pixel resolution for sand particles size and shape analysis
(Elsevier, Amsterdam, 2016)
In this paper, the influence of different scanning resolutions and the use of image analysis softwares for the image analysis, SigmaScan Pro, Image) and Matlab, on size and shape factors commonly used in particles ...
Hydrodynamic modeling of downward gas-solids flow. Part I: Counter-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward counter-current gas-solids flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. ...
Tailoring of magnetite powder properties for enhanced phosphate removal: Effect of PEG addition in the synthesis process
(Elsevier Science Bv, Amsterdam, 2016)
This study demonstrates that PEG-assisted hydrothermal synthesis provides a convenient and eco-friendly route to fabrication of mesoporous magnetite with enhanced capacity for phosphate removal, excellent potential for ...
Properties of quenched LiFePO4/C powder obtained via cellulose matrix-assisted method
(Powder Technology, 2013)
In this study, nanocrystalline LiFePO4/C composite powder has been synthesized via a cellulose matrix-assisted method. In an experiment conducted under extreme conditions involving rapid heating, short high-temperature ...
Prediction of the choking velocity and voidage in vertical pneumatic conveying of coarse particles
(Elsevier, 2006)
A method for predicting the choking velocity and voidage in vertical pneumatic conveying of coarse particles is developed and verified using the data obtained in this study as well as the data of Capes and Nakamura [C.E. ...
Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
