Fluid Computer Elements - Digital

A preliminary program to develop fluid logic elements suitable for general use in digital computer circuits was completed. The fluid mechanics stability mechanisms available for implementing the necessary logic functions were reviewed, and the attachment of a two-dimensional, incompressible jet was selected as the stability mechanism for memory flip/flops and OR/NOR logic elements. Functional requirements were established, and corresponding design criteria were evolved. The basic element geometry was established, and compact logic circuits employing as many as twenty elements were designed, built, and successfully operated using the developed hardware.
