This paper describes our findings regarding the accumulation of motile bacteria at the rear of a confined obstacle and the physical description of the mechanisms at play. We found that the modification of flow due to the presence of the obstacle prod

We study the mixing dynamics of a dyed and a clear miscible fluid by an oscillating flow inside an Hele-Shaw cell with randomly distributed circular obstacles. A transparent setup allows us to analyze the distribution of the two fluids and the revers

The instability of an iso-dense non-Brownian suspension of polystyrene beads of diameter 40 μm dispersed in a water-glycerol mixture submitted to a periodic square wave oscillating flow in a Hele-Shaw cell is studied experimentally. The instability

Miscible tracer dispersion measurements in transparent model fractures with different types of wall roughness are reported. The nature (Fickian or not) of dispersion is determined by studying variations of the mixing front as a function of the distan

Tracer dispersion is studied experimentally in periodic or disordered arrays of beads in a capillary tube. Dispersion is measured from light absorption variations near the outlet following a steplike injection of dye at the inlet. Visualizations usin
This work focuses on the influence of the relative humidity (essentially due to atmospheric conditions) on themany granular media behaviours. To this end, the experimental evolution of the avalanche characteristic anglesof continually tilted granular

The dispersion phenomenon of a polymer solution (scleroglucane) in a porous medium has been studied using radioactive techniques. Three different experiments were performed. In Experiment I a free tracer (I 131 Na no bounded) was dissolved into the p

We report here a study of the transport and tracer dispersion properties of fluids in a model of fractured media. The tracer dispersion process was analyzed using Newtonian and non-Newtonian fluids (polymeric solutions). Experiments were carried out

A new method based on transfer rate measurements of a radioactive solute inside activated carbon grains is presented which allows to isolate the relative contributions of the chemical (reversible adsorption) and geometrical (tortuous di!usion paths)

A new method based on radioactive dispersion is reported which permits the accurate determination of the parameters which describe the transport and exchange mechanisms for packed beds of porous particles: characteristic exchange time between the int
