Abstract: Paper investigates properties of very small, sub-millimetre sized gas bubbles in liquids,which are generated by oscillation produced by a fluiidic no-moving-part oscillato in the gas supply into the aerator. Of particular interest is the tendency of microbubbles to coalesce already while in immediate neighbourhood of the aerator exit. Another investigated property is oscillation driven by released surface energy. Autorr derived an equation describing the natural frequencty of the oscillation and with the help of this equation found interesting parameters of the processes, such as the amount of outside water that takes part in the oscillation and has a decisive role in the inertial properties of the variations of the microbubble shape.
