A method and apparatus for producing a liquid disperse system in a flow-through channel is described. The flow-through channel has first and second chambers. The liquid in the first chamber is maintained at a steady pressure P.sub.1. The liquid is passed through a localized flow constriction creating cavitation liquid jets that flow into the second chamber. The dynamic pressure of the liquid jets is govern by the equation .rho..nu..sup.2 /2.gtoreq.0.15 P.sub.1 where .rho. is the density of the cavitation liquid jet and .nu. is the velocity of the cavitation jet. Cavitation bubbles are produced in the cavitation liquid jets between 1.times.10.sup.-6 m and 1.times.10.sup.-2 m. The pressure in the second chamber P.sub.2 is maintained such that P.sub.1 /P.sub.2 is .ltoreq.9.8. The liquid disperse system is produced by the collapsing of cavitation bubbles under static pressure P.sub.2 in the second chamber. The pressure P.sub.2 in the second chamber is maintained by a localized resistance at an outlet of the second chamber. The localized flow constriction 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.
