3D Simulation and Validation of a Lab Scale Bubble Column
Chemical Engineering Transactions, 2015 Bubble columns are widely used in the chemical, petrochemical and biochemical industry. The correct prediction of the fluid dynamics, gas hold-up and bubble size distribution is of importance for the design and development of such reactors.

Considerations on bubble fragmentation models [PDF]
, 2010 n this paper we describe the restrictions that the probability density function (p.d.f.) of the size of particles resulting from the rupture of a drop or bubble must satisfy.

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).

Numerical Simulation of Hold-up and Velocity Profiles for Two-phase Developed Flows in a Column
Chemical Engineering Transactions, 2021 The purpose of this article is to simulate and analyse two-phase fluid dynamics in a bubble column, through two different numerical approaches, in a fast and effective way, to minimize project costs and increase productivity.

Protocol for quantifying miRNA trafficking across the endosomal membrane
FEBS Open Bio, EarlyView.An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.
