Journal ArticleDOI
Experimental study of liquid spreading in structured packings
TL;DR: In this paper, liquid hold-up and retention map measurements have been performed for two fluid systems: Air / Water and Air / MEA 30wt., and a correlation that relates global liquid holdup and liquid load taking into account liquid viscosity is proposed.
Journal ArticleDOI
Eulerian–Eulerian two-fluid model for turbulent gas–liquid bubbly flows
TL;DR: In this article, the Eulerian-Eulerian two-fluid model is adapted to bubble flows and a turbulence model adapted to bubbly flows is developed, in which the Reynolds stress tensor of the continuous phase is split into two parts, a turbulent dissipative part produced by the gradient of mean velocity and by the wakes of the bubbles, and a pseudo-turbulent non-dissipative part induced by the displacements of bubbles: each part is predetermined by a transport equation.
Journal ArticleDOI
Experimental study of the unsteady structure of a confined bubble plume
Judith Rensen,Véronique Roig +1 more
TL;DR: In this paper, the authors present an experimental study of two-dimensional bubble plumes confined in a tank and observe the non-stationary behavior of the flow with optical fiber probes and video camera measurements.
Journal ArticleDOI
Dynamics of a high-Reynolds-number bubble rising within a thin gap
TL;DR: In this article, an experimental analysis of path and shape oscillations of an air bubble of diameter d rising in water at high Reynolds number in a vertical Hele-Shaw cell of width h is presented.
Journal ArticleDOI
Liquid dispersion in packed columns: experiments and numerical modeling
TL;DR: In this article, the authors developed closure laws that can be implemented in CFD codes for Mellapak 250.X packing via gamma-ray tomography measurements, which can be used to predict liquid dispersion.
