TWO-FREQUENCY VORTEX GENERATOR Russian patent published in 2000 - IPC

FIELD: acoustic technique, possibly vortex generators suitable for using in coal mining, metallurgical, food making and other industry branches. SUBSTANCE: two-frequency vortex generator includes inlet branch pipe, two cylindrical vortex chambers at both side of branch pipe. Said chambers have different volumes and(or) curvature radius values. Volumes and heights of vortex chambers are determined by relation h₂V₁/h₁V₂>10⁴. For chambers with the same height their curvature radius values are determined by relation R1/R2 R₁/R₂>10². EFFECT: enhanced efficiency of technological influence of acoustic cavitation due to common action of acoustic two-frequency fields. 3 cl, 1 dwg
