fluidics, n. pl.|fluːˈɪdɪks|
[f. fluid n. after electronics, mathematics, etc.]
A field of technology concerned with using small interacting flows and jets of fluid in systems of tubes, nozzles, and cavities that have few or no moving parts, to carry out operations characteristic of electronics, such as amplification and switching.
Quot. 1960 represents a different sense.
[1960Compressed Air & Hydraulics Apr. 149/1 [Abstract of a paper by H. Masheder read at the 2nd European Fluid Power Conf., 28 Apr. 1960.] This paper examines future trends in automatic fluid power control in the light of the following factors: the reasons for the unique position occupied by fluidics; the stability of this position and whether it is likely to be threatened by competitive non-fluidic systems; [etc.]. Ibid. 171/2 One prominent engineer [sc. Masheder]..suggests ‘fluidics’ with which to designate all aspects of the behaviour of liquids and gases. ]1965Missiles & Rockets 8 Feb. 18/1 In five short years, with an investment of some $30 million, the United States has brought into being a new technology—fluidics. Ibid. 18/2 The term ‘fluidics’ as used throughout this report refers to that field of technology that deals with the use of fluids, either gaseous or liquid, in motion to perform functions such as signal or power amplification, temperature or rate sensing, logic or computation, and control. Inherent in the term is the concept of achieving amplification or gain—and often, the absence of moving parts. 1965Humphrey & Tarumoto Fluidics iii. xiv. 139 Fluidics will have significant applications in control valves; temperature, pressure and flow sensing and control systems;..and in small, low speed process computers. 1966Times 6 Dec. 20/6 The technique of fluidics..is based on a method of controlling the flow of either gases or liquids just as electron flow is controlled and amplified in electronic circuits. 1967New Scientist 19 Jan. 143/1 The analogy between fluidics and electronics has been taken one step further with the introduction of a planar turbulence amplifier. 1970Engineering 13 Mar. 268 Moving-part fluidics using membrane elements is little practised in the West. |
