Recently discovered possibility of generating sub-millimetre bubbles by means of pulsating the inlet gas flow by a fluidic oscillator has opened a way to many interesting and advantageous engineering applications. Some of them have been known before, but were too inefficient and nearly forgotten. Now they deserve discussing in the new perspective. Other, applications, new ones, appear now in literature at a rapid pace. This paper, by providing a survey of already existing possibilities and advantages, aims at providing the readers an inspiration for their own developments.
