E-raamat: Fluidic Oscillators and their Applications

Fluidic oscillators are generators of periodic fluid motion operating without moving mechanical components or elastically deformed parts. Years ago, this would not have been a topic worthy of writing a book. Fluidic oscillators were invented eighty years ago and practically forgotten soon after. Their recent reinvention, making them the topic of many research works and publications, is due to their capability to generate microbubbles in a very simple manner. The use of small bubbles can increase efficiency in applications such as microbiology, however up until now, there has been no way of making their production energy efficient. Even when they are produced by air flow in small diameter orifices, the generated bubbles are relatively large due to mutual conjunctions. What fluidic oscillators - which are small, reliable, durable and easy to make actually do is suppress the bubble conjunctions. Following from recent fluidic oscillator innovations, this book aims to explore their applications in greater depth.
