Hydrodynamic Characteristics of a Gas- Liquid –Solid Fluidized Bed Containing a Binary Mixture of Particles [PDF]
Engineering and Technology Journal, 2009 The present work is an experimental study on the effect of solid loading andsolid properties of both single and binary mixtures on the hydrodynamic parameters(gas holdup and bubble dynamics) of a fluidized bed bubble column. The experimentswere performed

Dynamics of a three-phase upflow fixed bed catalytic reactor [PDF]
, 1999 A dynamic model of an upflow fixed-bed catalytic reactor is developed to examine numerically transient axial temperature and concentration profiles obtained for the consecutive hydrogenation of 1,5,9-cyclododecateriene on a Pd/Al2O3 catalyst.

Similitude Analysis for Gas-Liquid-Fiber Flows in Cocurrent Bubble Columns [PDF]
, 2006 Gas-liquid-fiber systems are different from conventional gas-liquid-solid systems in that the solid material (i.e., fiber) is flexible, has a large aspect ratio, and forms flocs or networks when its mass fraction is above a critical value.

Comprehensive experimental investigation of counter-current bubble column hydrodynamics: Holdup, flow regime transition, bubble size distributions and local flow properties [PDF]
, 2016 In this paper, we apply a variety of experimental techniques to investigate the influence of the counter-current mode on bubble column hydrodynamics. We study an air-water bubble column, which is 5.3 m in height and has an inner diameter of 0.24 m, and ...

Characteristics of stratified flows of Newtonian/non-Newtonian shear-thinning fluids
, 2017 Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids in horizontal and inclined channels are presented. An iterative algorithm is proposed to compute the laminar solution for the general case of a Carreau non ...
