METHOD OF FLUID FLOW VIBRATION GENERATION AND VIBRATION GENERATOR FOR METHOD IMPLEMENTATION Russian patent published in 2014 - IPC F15B21/12 B06B1/20 

FIELD: power industry.

SUBSTANCE: method of fluid flow vibration generation involves preliminary separation of fluid in main supply pipeline (11) to two flows outside of whirlpool chamber (1), inside which the flows are whirled by channels with different flow rates in opposite directions and separated by partition (4) with through channel (5). The flow is whirled by swirl channels (2) at large flow rate. Flow with smaller flow rate is whirled by swirl channels (3) of opposite orientation and linked through channel (9) with chamber of adjustable elasticity (8) closed by tight elastic shell (10) and installed in pipe (7) lengthwise. Due to elastic interaction, fluid in channel (9) obtains an impulse directed to whirlpool chamber (1), so that whirled flows are decelerated abruptly, and flow through output nozzle (6) rises significantly.

EFFECT: enhanced efficiency of constant fluid flow conversion to pulse flow due to reduced hydraulic loss and hydraulic energy consumed.
