Design of Fluidic Element for Hydraulic Oscillators

The fluidic element used in hydraulic oscillators can meet the pressure oscillation amplitude and frequency requirements for oil well plugging.This paper mainly introduces the principle of wall-attached bistable fluidic element,elaborates on the design methods of the fluidic element,including the size and position of nozzles,control road,potential difference,flare angle,and so on.At last,the paper explains the concept of each parameter and its impact on the fluidic element performance in brief.
