Chapter and Conference Paper
Trajectories of Water and Sand Jets
In this paper we introduce a correlation for the trajectories of sand jets, of a non-cohesive granular material, emerging from vertical sidewall orifices of diameter D and wall thickness w. A contrast with water ...

Experimental Study of a Vortex Generated at the Edge of a Channel with a Step
At the outlet of estuary-like systems, three vortices are formed: a dipole and a spanwise vortex. The spanwise vortex is formed due to the separation of the bottom boundary layer, just in front of the dipole. ...

Design and Evaluation of an Afforestation Project Based on Geopedologic and Ecological Information in North-Western Patagonia, Argentina
Forest plantations can positively influence ecosystem patterns and processes, but afforestation based on monocultures can also affect plant diversity and should therefore be soundly designed. In the Aguas Fría...

Capillary Rise in a Taylor-Hauksbee Cell with a Tilted Edge
In this work we discuss a series of experiments to get the equilibrium profiles when a viscous liquid rises spontaneously in the wedge-shaped gap between two vertical plates intersecting at a tight angle ...

Isotherms of Natural and Forced Convection Around a Heated Horizontal Cylinder Embedded in a Porous Medium
This work presents an experimental analysis of free and forced convection due to a heated cylinder in a fluid-saturated porous medium. The resulting features of the temperature distribution under the action of...

Mass Flow Rate of Granular Material from an L-Valve Without Aeration
In this work we introduce a correlation to estimate the mass flow rate from an L-valve, without aeration, but under gravity flow, of a non-cohesive granular material. This criterion is based on the mass flow r...

Chapter and Conference Paper
Flows from Bins: New Results
Gravity granular flows of cohesionless materials emerging from bottom exits and from lateral exit holes, both in vertical bins, and from face walls in tilted bins were modeled and measured. The models are base...

Experimental Study of Heat and Mass Transfer During Steam Injection in Homogeneous Porous Media
We carry out experiments in which we have already measured, in a short period of time, the physical parameters that appear during the steam injection in a homogenous porous media (Woods and Fitzgerald 1993). For ...

Experiments of Mercury Jets Im**ing on Water
In this work we have analyzed experimentally the impact of mercury jets on water surfaces, i.e., between liquids having a high contrast in their densities and their surface tensions. Mercury jets can have diff...

Chapter
Random Forces on Obstacles in Channels with Grains: A Mechanical Analogy of Crowd Disasters
In this work we have studied experimentally, through sensitive force measurements, the fluctuating forces on a rigid obstacle located at the middle of a horizontal channel, when a two-dimensional (2D) granular...

Experimental Study of the Growth of Bubbles in Corrugated Tubes
In this chapter we study some experiments with different liquids to validate theoretical results on the growth of bubbles in corrugated pipes. These experiments were performed using a high range of capillary n...

Experimental Studies of a Steam Front in a Radial Porous Cell
In many Geothermal reservoirs water is injected through porous media in order to obtain steam. This process is basically used to generate geothermal energy. It could be expected that the water or steam injecte...

The Boundary Element Method in Fluid Mechanics: Application to Bubble Growth
The origin of the numerical implementation of boundary integral equations can be traced from fifty years earlier, when the electronic computers had become available. The full emergence of the numerical techniq...

Geostatistical Inverse Problem: A Modified Technique for Characterizing Heterogeneous Fields
This paper describes a modification of the self-calibrating method for generating equally likely realizations (conditional simulations) of the transmissivity field, that honour measurements of transmissivity a...

Inverse Geostatistical Modeling of Pum** and Tracer Tests Within a Shear-Zone in Granite
A numerical model of the hydraulic conditions within a heterogeneous shear-zone has been built using a geostatistical inverse approach for the analysis of static heads and pum** tests. Results indicate the e...

Interpretation of Field Tests in Low Permeability Fractured Media. Recent Experiences
We have been treating fractured media as the result of embedding conductive 2D fractures in a 3D continuum medium. Automatic calibration has normally succeeded in producing models capable of predicting indepen...

Geostatistical Formulations of Groundwater Coupled Inverse Problems
Geostatistical formulations of groundwater inverse problems are based on treating one or several model parameters as regionalized variables and have proven useful for groundwater flow. Extension to coupled flo...
