Interface debonding driven by fluid injection in a cased and cemented wellbore: Modeling and experiments

The integrity of the wellbore completion under injection conditions is vital for the effective, long term storage of carbon dioxide. Here we experimentally demonstrate and mathematically model fluid-driven debonding of the wellbore annulus in order to prov ...

EXPERIMENTAL VALIDATION OF A CONSTANT SURFACE SHEAR STRESS IN PARTICLE SALTATION LAYERS

Benjamin Andreas Walter

Owens second hypothesis [1] states that the surface shear stress induced by the fluid on the stationary sediment on the ground in a particle saltation layer equals the threshold for particle entrainment. Despite the fact that most numerical models describi ...

Laboratory-scale dam-break study of gravity currents with basal entrainment: PIV measurements of a viscous newtonian fluid over a horizontal bed of the same ﬂuid.

Christophe Ancey, Belinda Margaret Bates

Geophysical gravity flows such as avalanches and debris flows belong to a special class of hazardous environmental event, in which a mixture of solids and fluids (e.g. debris and mud, snow and air) flow as a liquid and may run out much further than expecte ...

Microscale Adiabatic Gas-Liquid Annular Two-Phase Flow: Analytical Model Description, Void Fraction, and Pressure Gradient Predictions

John Richard Thome, Lorenzo Consolini, Andrea Cioncolini, Chin Lee Ong

The study is devoted to the modeling of microscale adiabatic gas-liquid annular two-phase flow. The turbulent diffusion of momentum in the annular liquid film is assumed to be governed by the conditions near the channel wall, in analogy with single-phase t ...

On-Chip Nanoplasmonic-Nanofluidic Biosensors Overcoming Mass Transport Limitations

Hatice Altug, Min Huang

We demonstrate a novel hybrid platform merging label free nanoplasmonic sensing with actively controlled nanofluidic surface delivery to overcome mass transport limitations. We show 14-fold improvement in mass transport rate constants appearing in the expo ...

Novel plasmonic biosensors molding the flow of light and fluidics at subdiffraction limit

Hatice Altug, Min Huang

We introduce a novel hybrid platform merging label free nanoplasmonic biosensing with actively controlled nanofluidic analyte delivery to overcome mass transport limitations. We show 14-fold improvement in mass transport rate constants appearing in the exp ...

Multiscale Computational Methodology Applied to Hydroacoustic Resonance in Cavitating Pipe Flow

Nicolas Ruchonnet

The present work is a contribution to the physical analysis and numerical simulation of the pressure surges in hydraulic machinery and connected conduit systems. Localized hydrodynamic instabilities including cavitation are prone to interact with the entir ...

Constructal tree-shaped microchannel networks for maximizing the saturated critical heat flux

John Richard Thome, Rémi Revellin

A constructaltree-shaped microchannel network for maximizing the saturated critical heat flux in a disc-shaped planar body has been investigated. n(0) radial channels touch the center and n(p) channels touch the periphery. Designs with no pairing level (n( ...

Critical Heat Flux During Flow Boiling in Microchannels: A Parametric Study

John Richard Thome, Rémi Revellin

The application of flow boiling in microchannels in copper cooling elements for very high heat flux dissipation from microprocessor chips is one of the promising technologies to replace air cooling and water cooling of these units, particularly in mainfram ...

Experimental results of a 70 kA high temperature superconductor current lead demonstrator for the ITER magnet system

Rainer Wesche

In the frame of the European Fusion Technology Programme, the Forschungszentrum Karlsruhe and the CRPP Villigen have designed and built a 70 kA current lead for the ITER TF Coils using High Temperature Superconductors (HTS). At the beginning of 2004 the HT ...
