Effect of surfactant on homogeneous regime stability in bubble column
TL;DR: In this paper, the effect of surface active agents on homogeneous-heterogeneous flow regime transition in a laboratory scale bubble column was investigated and the critical point where the homogeneous regime loses stability and the transition begins was evaluated by several methods.

The removal of CO2 from biogas using a laboratory PSA unit: design using breakthrough curves
TL;DR: In this paper, a laboratory scale PSA unit is introduced to construct the fixed bed adsorption layer, and the maximum sorption capacity of CO2 and CH4 was determined from a high pressure thermogravimeter.

The effect of the draft tube geometry on mixing in a reactor with an internal circulation loop – A CFD simulation
TL;DR: In this paper, the effect of geometrical parameters on mixing time in a reactor with an internal circulation loop is described, and the results of experimental measurements (liquid velocity and gas hold-up) obtained on the laboratory scale reactor are compared with the CFD simulations.

End effects in rotational viscometry I. No-slip shear-thinning samples in the Z40 DIN sensor
TL;DR: In this article, the authors tackle the end effect for the standard sensor Z40 DIN according to the ISO 3219 by solving the related 2D boundary-value problem for a class of shear-thinning viscosity functions.

On Bubble Rising in Countercurrent Flow
TL;DR: In this article, a single bubble was placed in downward diverging flow of low and moderate viscous liquids (aqueous solutions of glycerine and of electrolytes (NaCl, Na3PO4, MgSO4), and butanol).
