Abstract: A nozzle 30 including a body having a flow inlet and a flow outlet. The nozzle also includes a converging section 32 having a decreasing diameter positioned adjacent the flow inlet, an orifice 33 positioned at a narrow end of the converging section, an intermediate section 35 having a constant diameter positioned adjacent the orifice, and a diverging section 36 having an increasing radius positioned adjacent the intermediate section and the flow outlet. Flow of a liquid through the nozzle results in a flow rate increase of the liquid within the converging section, and a subsequent flow rate decrease of the liquid in the diverging section, thereby facilitating particle dispersion within the liquid.

Abstract: An apparatus for dispersing particles (P) in a fluid (F), comprising: a flow divider (10) for receiving the fluid (F) and for separating the fluid (F) into a first fluid stream (F1) and a second fluid stream (F2); first and second fluid branches (11, 12) for receiving the fluid streams (F1, F2); a branch joining section (14) for receiving the fluid streams (F1, F2), the branch joining section (14) having a collision zone (141) for allowing the first and second fluid streams (F1, F2) to collide; a first nozzle (30) that is arranged in the first fluid branch (11); and a second nozzle (40) is arranged in the second fluid branch (12), the first nozzle (30) comprising an orifice (33) that is followed by a fluid diverging section (36).
