Gas-liquid mass transfer : influence of sparger location [PDF]
, 2004 The performance of three sparger diameters (DS = 0.6D, DS = D, DS = 1.6D) in combination with three positions (below, above or level with the impeller) for gas-liquid dispersion and mass transfer were evaluated in the case of the Rushton turbine and the ...

Axial dispersion in curved channels in the presence of pulsating flow [PDF]
, 2022 A narrow residence time distribution (RTD) is desirable in several chemical engineering processes. However, in systems operating at low Reynolds number, axial dispersion can be significant.

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

Effect of Axial Agitator Configuration (Up-Pumping, Down-Pumping, Reverse Rotation) on Flow Patterns Generated in Stirred Vessels [PDF]
, 2001 Single phase turbulent flow in a tank stirred with two different axial impellers - a pitched blade turbine (PBT) and a Mixel TT (MTT)- has been studied using Laser Doppler Velocimetry. The effect of the agitator configuration, i.e.

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

Liquid-Phase Back mixing in Bubble Columns
Tikrit Journal of Engineering Sciences, 2010 Liquid-phase axial dispersion coefficients have been measured for air-water system in bubble columns of 10, 15 and 30 cm diameter. The experiments are carried out using a transient method (the tracer response method).

Hydrodynamics and axial mixing in a packed gas-liquid column [PDF]
Acta Periodica Technologica, 2003 The objective of this study was to investigate the pilot-plant gas absorption packed column hydrodynamics, as well as axial mixing in the system air-water. The pressure drop and the gas phase holdup data were determined in dependence on the flow rates of
