Visualization of steam injection into homogeneous porous media
In this study we describe the important features of the process of steam injection through non-consolidated porous media made of sand. We have analyzed the resulting fluid flow patterns through normal and infr...

Visualization of isotherms around a heated horizontal cylinder embedded in a porous medium
Experiments reported here confirm experimentally the existence of the characteristic planar buoyant plumes that emerge as a consequence of the presence of a cylindrical heat source embedded in an homogeneous a...

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. ...

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...

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...

Porous media convection between vertical walls: continuum of solutions from capped to open ends
Natural convection in a vertical slot filled with a fluid-saturated porous medium modeled by the Brinkman equation is considered. A continuum of solutions are found from capped to open ends in fully-developed ...
