<p>PCT No. PCT/US93/07931 Sec. 371 Date Feb. 21, 1995 Sec. 102(e) Date Feb. 21, 1995 PCT Filed Aug. 24, 1993 PCT Pub. No. WO94/04275 PCT Pub. Date Mar. 3, 1994High-shear treated materials are passed through a high-shear treatment zone which allows the coexistence of free supra-Kolmogoroff eddies larger than the smallest possible Kolmogoroff eddy diameter and forced sub-Kolmogoroff eddies smaller than this diameter. This zone includes a subsidiary higher-shear zone for suppressing these free eddies. The passage walls (40, 44, 102, 108) move relative to one another transverse to the flow to force the simultaneous development of supra-Kolmogoroff and sub-Kolmogoroff eddies while maintaining liquid films adherent to the passage surfaces. The movement produces only forced sub-Kolmogoroff eddies in the subsidiary zone while maintaining a non-turbulent flow. Ultrasonic oscillations (52) may be applied to cause elastohydrodynamic pressure and viscosity increases and/or production of smaller sub-Kolmogoroff eddies. One apparatus includes an inner cylinder rotatable (46) inside a hollow outer cylinder (38), another consists of tow circular coaxial plates, and the rotational axis can be vertical or horizontal.</p> |
