Particle velocities in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier, Amsterdam, 2013)
Particle velocities have been measured in two-dimensional water fluidized beds of mono-sized spherical glass particles d(p) = 1.94, 2.98, 4.00 and 6.00 mm in diameter. For each particle size, a separate column was constructed ...
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-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 ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier Science Bv, Amsterdam, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
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-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. ...
Particle characterization of polydisperse quartz filtration sand
(Elsevier Science Bv, Amsterdam, 2014)
In this paper, different methods for particle characterization were applied to 16 polydisperse fractions of quartz filtration sand obtained by sieving, with sieve diameters in the interval d(m) = 0359 to 2.415. For each ...
Influence of the synthesis parameters on the properties of the sepiolite-based magnetic adsorbents
(Elsevier Science Bv, Amsterdam, 2017)
The magnetic nanocomposites (MNCs), used as adsorbents for Cd2+ ions, were prepared by a co-precipitation method using both the untreated natural (SEP) and the partially acid-activated (ASEP) sepiolites as supports for ...
Wall effects on the velocities of a single sphere settling in a stagnant and counter-current fluid and rising in a co-current fluid
(Elsevier, Amsterdam, 2010)
Experimental results were obtained on the steady settling of spheres in quiescent media in a range of cylindrical tubes to ascertain the wall effects over a relatively wide range of Reynolds number values. For practical ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
