Bubble dynamics and deformation in microgravity

Le Journal de Physique IV, 2001
Studies on two-phase flows have been performed at the Institut de Mecanique des Fluides de Toulouse for the past ten years, to improve the knowledge of the two-phase gas-liquid flows in normal and microgravity conditions, in order to optimize the design of the terrestrial and space thermohydraulic systems (evaporators, condensers, heat exchangers ...

Effect of bubble deformation on stability and mixing in bubble columns

Chemical Engineering Science, 2002
Abstract The paper deals with hydrodynamics in bubble columns. The objective of the paper is to study stability and mixing in a bubble column. The modeling of parameters such as stationary drag and added mass is addressed. In addition, the effect of bubble deformation in terms of eccentricity is highlighted.

Increase of effective viscosity in bubbly liquids from transient bubble deformation

Fluid Dynamics Research, 2008
The effective viscosity of bubbly liquids is measured using the Stokes drag of a falling sphere, i.e. falling sphere viscometry. This method can evaluate the influence of a bubble's transient deformation. Viscosity relative to a single-phase fluid is directly obtained by the terminal falling velocities of the sphere. When bubbles are distributed around

Marginal stability curve of a deformable bubble

International Journal of Multiphase Flow, 2017
Abstract We present a marginal stability curve of a deformable bubble ascending freely in a viscous Newtonian liquid. The bubble is considered in the limit of zero gas/liquid density and viscosity ratio as an incompressible void of deformable shape.

On the deformation of quartz containing bubbles

Journal of the Geological Society, 1978
Analysis of the interaction of dislocations with bubbles in quartz indicates that the distribution of bubbles during deformation is critically important to the deformation of quartz by dislocation processes. The estimated stress necessary to ensure large scale dislocation movement in inclusion rich quartz (bubbles and voids in the case considered here)

Interactions of Cavitation Bubbles with Deformable Interfaces

2023
Cavitation is a topic that has long been of interest due to the large and growing range of applications associated with it. This is mainly because the collapse of cavitation bubbles releases a considerable amount of energy into the surrounding environment.

Deformable bubbles in a free shear layer

International Journal of Multiphase Flow, 1997
The flow in and around three-dimensional deformable bubbles subjected to a non-linear planar free shear layer was simulated using a finite difference/front tracking scheme with the full Navier-Stokes equations including surface tension. This allowed detailed resolution of the flow around and inside the bubble.

Bubble deformation in an electric field

Journal of Engineering Physics, 1979
The problem of expansion of bubbles in a compressible liquid upon application of an electric field is solved. The effect of the electric field on phase transition is evaluated.

Dynamic wall deformation in bubble garnet material

Journal of Applied Physics, 1980
The dynamic diffuse wall (DDW) structure discovered previously in bubble material using high-speed photography has been investigated in detail here. The reflection (Kerr) mode is used to study the wall dynamics at the surfaces and the results are compared to the transmission (Faraday) mode which shows wall dynamics in the bulk of the film.
