TL;DR: In this paper, a fluidic oscillating nozzle that oscillates a fluid jet at high frequency by the use of fluidic amplification technology with no moving parts is described, but its appearance is that of a fan-type jet that disperses at a fan angle from the nozzle.
Abstract: A fluidic oscillating nozzle that oscillates a fluid jet at high frequency by the use of fluidic amplification technology with no moving parts. The jet that issues from the nozzle is a zero-degree jet of fluid that maintains a very high energy density; however, due to its oscillation, its appearance is that of a fan-type jet that disperses at a fan angle from the nozzle. At a nominal distance from the nozzle, the jet covers the surface with a relatively broad area of flow while maintaining high energy impact density due to the impact effects of the non-expanding zero-degree jet.

TL;DR: The fluidic pump is a type of positive displacement pump in which basic fluid mechanics phenomena are utilized to eliminate valves and other moving parts that are exposed to the fluid being transferred as discussed by the authors.
Abstract: The fluidic pump is a type of positive-displacement pump in which basic fluid mechanics phenomena are utilized to eliminate valves and other moving parts that are exposed to the fluid being transferred The version described in this article is powered by gas pressure serving as gas pistons and is virtually maintenance-free It utilizes two displacement vessels and is designed to produce a steady and continuous liquid flow This type of pump may be very useful for the transfer of radioactive or hazardous liquids where mechanical maintenance may be difficult or exposure of personnel to the fluid is undesirable This paper presents experimental and model-predicted characteristics of such systems The effects of several geometric parameters and operating conditions on the performance of the pump are briefly discussed
