EXPERIMENTAL STUDY OF LIQUID DISPERSION IN BUBBLE COLUMN

open access: yesDiyala Journal of Engineering Sciences, 2008
The main object of this study is to investigate the influence of column diameter and superficial gas velocity on liquid phase dispersion coefficients (axial and radial dispersion coefficients), mixing times, gas holdup, and bubble dynamics (bubble ...

Analysis of Liquid Flow and Mixing in an Oscillatory Flow Reactor Provided with 2D Smooth Periodic Constrictions

open access: yesU.Porto Journal of Engineering, 2018
In this research paper the residence time distribution (RTD) was monitored for a range of fluid oscillation, frequency, amplitude and flow rate in two oscillatory flow reactors (OFR) provided with 2D smooth periodic constrictions (2D-SPC) with different ...

Dispersion in oscillatory flows [PDF]

open access: yes, 1983
The enhanced axial mixing which is caused by dispersion in oscillatory flows in some mass transfer devices may limit the reactor performance. This effect has provided the motivation for the present study in which oscillatory flow dispersion in a flat ...

Modeling ofMixing in The Liquid Phase For Bubble Column [PDF]

open access: yesEngineering and Technology Journal, 2009
Hydrodynamic characteristics (mixing in the liquid phase) in a bubble column with a non-Newtonian liquid phase (aqueous solutions of carboxymethylcellulose, or CMC, at different concentrations) were measured and correlated.

Liquid-phase RTD studies in a flotation column: an analysis between tanks-in-series and axial dispersion models

open access: yesREM: International Engineering Journal, 2021
The objective of the present study is to evaluate the fluid dynamics of a flotation column (2" in diameter and 6 m in height) based on gas hold-up measurements and, in particular, by applying the liquid-phase RTD (residence time distribution) technique ...

Modeling of particle segregation in a rotating drum [PDF]

open access: yes, 2010
Mixing of granular solids is a processing step in a wide range of industries. The fundamental phenomena in granule mixing are still poorly understood, making it difficult to a priori predict the effectiveness of mixing processes.

Axial Dispersion and Back-mixing of Gas Phase in Pebble Bed Reactor

open access: yesTikrit Journal of Engineering Sciences, 2011
Despite the worldwide attended of pebble bed reactors (PBRs), there is a lack of fundamental understanding of the complex flow pattern. In this work, the non-ideal flow behavior of the gas phase, which is used, for cooling has been investigated ...

Design and Experimental Validation of a Ducted Counter-rotating Axial-flow Fans System [PDF]

open access: yes, 2012
An experimental study on the design of counter-rotating axial-flow fans was carried out. The fans were designed using an inverse method. In particular, the system is designed to have a pure axial discharge flow.

Axial dispersion of the liquid phase in a three-phase Karr reciprocating plate column [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
The influence of the gas flow rate and vibration intensity in the presence of the solid phase (polypropylene spheres) on axial mixing of the liquid phase in a three phase (gas-liquid-solid) Karr reciprocating plate column (RPC) was investigated. Assuming
