We characterize the assembly of microscopic particles in patterned beds. The particles are immersed in a liquid template generated by vibration. We study, at the same time, the waves in the liquid surface, and the topography of the bed. Results show

We report a study of droplet generation in two phase flows of non-miscible fluids in a T-shaped array of circular channels, at the mesoscale between micro- and milli-fluidics. Our experiments show that the balance between the different types of force

A systematic experimental study of the Faraday instability in viscoelastic fluid is presented. We have used a shear thinning polymer solution in which the elastic effects are predominant within our work range. We have analyzed the dependence of the t

A camera films a screen to which it is connected. It films its own image, feeding back the image to the screen. The camera can turn around an optical axis. A pattern of p light spots on the screen and q turns (feedback loops) of the camera appears, w

The equilibrium properties of a polymer solution in the vicinity of a solid-liquid interface are locally altered relative to those in bulk. Discrepancies between porous media and conventional rheology appear when the pore wall is either attractive or

Parametrically excited surface waves, well known as Faraday waves, are studied when finger structures are generated on the free surface. In this state, the surface breaks and ejects droplets from wave peaks when the applied force exceeds an accelerat

A fast and rapid chemical reaction is presented here for labelling the polysaccharide scleroglucan with iodine to simplify its detection. The conditions proposed for the chemical reaction (temperature, concentrations of reactants and pH) were selecte

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

Tracer dispersion in Newtonian and shear-thinning fluids (scleroglucan-water polymer solutions) flowing through single and double porosity grain packings has been studied experimentally using both classical transmission dispersion and echo dispersion
