Integral fluidic generator of microbubbles
Original language description
Very small gas bubbles dispersed in liquid are desirable in many applications. If smaller than 1 mm in diameter, they are called microbubbles. Until recently, the advantages they offer have been little usedbecause of generally low efficiency of microbubble generation methods. A solution was found in pulsating the gas flow into the submerged aerator by a fluidic oscillator. At present, the oscillator and aerator are separate devices. The flow pulsation is strongly damped in the connecting tubes. New solution presented in this paper relies on oscillator robustness and no need for maintenance, which allows integrating it with the aerator into a single body submerged in the liquid. Small bubble size requires driving frequency much higher than has been so far applied. The present paper shows some of the ways leading to high frequencies ? in particular the use of dominant third harmonic of the basic switching frequency.
