Fluidic Oscillators Mediating Generation of Microbubbles (Survey)

If a gas volume is distributed into many microbubbles of sub-millimetre size, the total gas/liquid surface becomes very large. This increases overall heat and/or mass transport across sum surfaces. The paper discusses several applications in which use efficiency various processes, especially wastewater treatment and growing microorganisms such as algae, yeast, bacteria, or primitive fungi. problem microbubble generation by percolation aerator their coalescence larger bubbles, whatever small are pores generated. solution this size discrepancy question was found agitating flow fluidic oscillator prior to its injection through aerator. no-moving-part device, simple, inexpensive, resistant external effects like acceleration heat, with long maintenance-free working life.
