Focus on a project

Structuration of a particle suspension oscillating in a Hele-Shaw cell

Time dependent motions of particle suspensions occur in many natural (e.g. seabeds) and industrial flows. We have shown that the concentration of a suspension of non Brownian iso-dense particles oscillating between transparent parallel plates may vary spatially in the direction parallel to the flow, giving rising to periodic transverse streaks. The analysis of the particle distribution in the aperture of the cell shows that there is first a segregation of the particles into a plane layer in the center of the aperture which becomes wavy and, then, the periodic structure appears.
