<p>A method and apparatus for producing a liquid disperse system in a flow-through channel is described. The flow-through channel (1) has first and second chambers (4, 5). The liquid in the first chamber (4) is maintained at a steady pressure P1. The liquid is passed through a localized flow constriction (2) creating cavitation liquid jets that flow into the second chamber (5). The dynamic pressure of the liquid jets is govern by the equation ςξ2/2≥0.15 P¿1? where ς is the density of the cavitation liquid jet and ξ is the velocity of the cavitation jet. Cavitation bubbles are produced in the cavitation liquid jets between 1 x 10?-6¿ m and 1 x 10-2 m. The pressure in the second chamber P¿2? is maintained such that P1/P2 is ≤9.8. The liquid disperse system is produced by the collapsing of the cavitation bubbles under static pressure P2 in the second chamber. The pressure P2 in the second chamber is maintained by a localized resistance at an outlet of the second chamber (5). The localized flow contriction may be shaped to produce cavitation liquid jets which are cylindrical, ring-shaped, or flat-shaped. The liquid flow may be passed through the flow-through channel a number of times to further increase the production of liquid disperse systems.</p> |
