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 ...
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 ...
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 ...
Analogy between momentum and heat transfer in liquid-solid fluidized beds
(Elsevier Science Bv, Amsterdam, 2015)
Wall-to-bed heat transfer in particulate fluidized beds of spherical particles was studied. Experiments were performed using spherical glass particles of 0.80-2.98 mm in diameter with water in a 25.4 mm I.D. copper tube ...
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 ...
Mass transfer in vertical liquid-solids flow of coarse particles
(Elsevier Science Bv, Amsterdam, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
Influence of synthesis parameters on the structure of boehmite sol particles
(Elsevier, Amsterdam, 2003)
Influence of the type and amount of acid, used for aluminium hydroxide peptization, on the crystallinity and specific surface area of the dispersed phase of boehmite sols as well as the pH of sols, was investigated. The ...
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. ...
