Small moving rigid body into a viscous incompressible fluid [PDF]

open access: yes, 2016
We consider a single disk moving under the influence of a 2D viscous fluid and we study the asymptotic as the size of the solid tends to zero.If the density of the solid is independent of $\varepsilon$, the energy equality is not sufficient to obtain a ...

Elements of Poro-Elasticity for Reservoir Engineering Éléments de poro-élasticité pour l'ingénierie de réservoirs

open access: yesOil & Gas Science and Technology, 2006
Poro-elasticity is introduced by establishing the parallel between the equations of elastic solid mechanics and the equations describing the single-phase flow of a fluid in a porous medium.

A Note on the Unsteady Cavity Flow in a Tunnel [PDF]

open access: yes, 1974
The unsteady internal cavitating flow such as the one observed in a pump or a turbine is studied for a simple two-dimensional model of a base-cavitating wedge in an infinite tunnel and it is shown how the cavitation compliance can be calculated using the

Transport des déblais en puits inclinés Transport of Cuttings in Directional Wells

open access: yesOil & Gas Science and Technology, 2006
Le but de l'étude est de définir des relations quantitatives facilement applicables pour optimiser le débit et la rhéologie du fluide de forage, selon l'inclinaison du puits. Les travaux ont comporté différentes parties : expérimentations de laboratoire,

Fluid transitions

open access: yesNeuropharmacology
Water is critical for survival and thirst is a powerful way of ensuring that fluid levels remain in balance. Overconsumption, however, can have deleterious effects, therefore optimization requires a need to balance the drive for water with the satiation of that water drive.

Influence of oxidizer flow speed on the toxic species composition in laminar diffusion flame under weightless conditions

open access: yesEmergency Management Science and Technology
The molecular species composition of major toxic species, such as soot, CO and unburnt hydrocarbons from a boundary layer diffusion flame over heptane or dodecane surface at microgravity is numerically investigated.

On the inviscid Boussinesq system with rough initial data [PDF]

open access: yes, 2014
We deal with the local well-posedness theory for the two-dimensional inviscid Boussinesq system with rough initial data of Yudovich type. The problem is in some sense critical due to some terms involving Riesz transforms in the vorticity-density ...
