Abstract
A device for fractionation of a fluid containing particles and extraction of a particle-lean volume and a particle-rich volume, including: a cylindrical reservoir including an inlet orifice to supply the reservoir with fluid in a pumping direction from first to second ends of the reservoir; a fractionation body extending along a central axis of the reservoir, an upstream end positioned in vertical alignment above the inlet orifice, a cross section of the fractionation body reducing sharply at its downstream end; the fractionation body defining, with the reservoir, a first passage opening at the downstream end onto a recirculation zone with a geometric singularity; and an extraction mechanism downstream of the fractionation body to separate and extract the lean and rich volumes, including a partition delimiting an extraction volume configured, as fluid circulates in the pumping direction, to receive the particle-lean phase formed in the recirculation zone.
