Abstract

Dangerous fluids must be kept properly contained. With standard pumps and flow control valves this may be a problem, especially in emergency situations which may be caused by material fatigue, seizing, screws getting loose, and similar situations requiring maintenance and repair. However well protected in standard regimes, during a repair and associated device disassembly the hazardous fluid may become exposed to the outside world. No-moving-part fluidics, practically maintenance-free, offers a solution - but it is, unfortunately, almost unknown. This survey aims at propagating the knowledge of these fluidhandling devices. Three classes of fluidic devices that are developed (mainly in nuclear engineering applications) specifically for handling dangerous liquids and gases are discussed: (A) Passive flow control valves, (B) Valves controlled by an external signal, and (C) Fluidic pumps driven by alternating flow
