Abstract:

Fluidics is a new branch of automation, the distinguishing characteristic of which is that of various functions of control, logic and computation both digital and analog operations, which had earlier been performed only by electronic devices, are performed using streams of air. The report analyzes the characteristics of the flows of air used to perform a number of operations amplification of continuous signals, relay switching, recording of discrete quantities, logic operations, and the generation of oscillations. These devices are based on the effects of stream interaction and the separation of streams from walls. Problems of the theory of jet elements using other aerodynamic effects such as flow turbulization, jet vortexing, etc. are also investigated. Methods of the design and experimental investigation of pneumatic jets, chambers and connecting channels, which are just as important as the jet elements themselves for pneumatics, are also described. These methods can be used for the performance of similar operations using streams of liquids. The appendix presents brief information from the applicable areas of hydroaerodynamics. Author
