Characterization of Bubbly Flow Systems: A Review

A Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid

The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced <span style="font-size: 10pt...

Turbulent Bubbly Flow

Characterization of Bubbly and Slug Flow Regimes Generated in a Minichannel in Microgravity Conditions

Abstract We performed a characterization of the bubbly and slug flow regimes in minichannels in conditions relevant to microgravity. Two-phase flows were generated on ground by means of a T-junction device (1 mm i.d.), whose operation is independent to changes in gravity level [1]. Air and water were injected at several superficial velocities ranging from 0 up to 2 m/s. The generation and detac...

Bubbly flow structure in hydraulic jump

In an open channel, a hydraulic jump is the rapid transition from superto sub-critical flow associated with strong turbulence and air bubble entrainment in the mixing layer. New experiments were performed at relatively large Reynolds numbers using phase-detection probes. Some new signal analysis provided characteristic air–water time and length scales of the vortical structures advecting the ai...

CFD Simulation of Bubbly Flow Through a Bubble Column

In this investigation, CFD simulation is presented to study the hydrodynamic of bubbly flow and mass transfer in bubble column using EulerianEulerian Multifluid approach with a standard kε turbulence model. unsteady state method for modeling the multiphase flow and mass transfer from air to de-aerated water and the column hydrodynamics. Understanding the complexity of the fluid dynamics and mas...
