The Mechanics of Bubble Growth and Rise in Sediments
نویسندگان
چکیده
The overall objective of our work is to understand bubble growth and rise in natural marine sediments. In the first phase of our study (to mid-2003) we demonstrated that bubbles grow and rise in sediments by the mechanism of fracture. The second (current) phase has aimed to develop methods to measure the mechanical parameters that control the fracture of soft sediment; these parameters, i.e., Young’s modulus, E, the critical stress intensity factor, K1c, Poisson’s ratio, ν, etc., are not routine measurements and geo-scientists have not developed means for their in situ measurement. These parameters are needed to solve our evolving model of bubble growth.

Release of multiple bubbles from cohesive sediments
[1] Methane is a strong greenhouse gas, and marine and wetland sediments constitute significant sources to the atmosphere. This flux is dominated by the release of bubbles, and quantitative prediction of this bubble flux has been elusive because of the lack of a mechanistic model. Our previous work has shown that sediments behave as elastic fracturing solids during bubble growth and rise. We no...
متن کاملExperimental investigation of bubble growth and detachment in stagnant liquid column using image – based analysis
An experimental study has been carried out to characterize bubble formation, growth, and detachment mechanisms in a stagnant liquid column. Both bubble frequency and bubble detachment size were measured in different gas flow rates, injector diameters and orientations, submergence height, and liquid properties. Experiments were performed for air injection flow rate ranges between 200 mlph and 12...
متن کاملCFD-DEM Investigation on van der Waals Force in Gas-Solid Bubbling Fluidized Beds
Effect of interparticle force on the hydrodynamics of gas-solid fluidized beds was investigated using the combined method of computational fluid dynamics and discrete element method (CFD-DEM). The cohesive force between particles was considered to follow the van der Waals equation form. The model was validated by experimental results from literature in terms of bed voidage distribution and Eule...
متن کاملNumerical Investigation of the Effect of Bubble-Bubble Interaction on the Power of Propagated Pressure Waves
The study of bubble dynamics, especially the interaction of bubbles, has drawn considerable attention due to its various applications in engineering and science. Meanwhile, the study of the oscillation effect of a bubble on the emitted pressure wave of another bubble in an acoustic field which has less been investigated. This issue is investigated in the present study using the coupling of Kell...
متن کاملStudy of Parameters Affecting Separation Bubble Size in High Speed Flows using k-ω Turbulence Model
Shock waves generated at different parts of vehicle interact with the boundary layer over the surface at high Mach flows. The adverse pressure gradient across strong shock wave causes the flow to separate and peak loads are generated at separation and reattachment points. The size of separation bubble in the shock boundary layer interaction flows depends on various parameters. Reynolds-averaged...
