Study of the Switching Mechanism in Bistable Amplifiers with Application to Their Development, Optimization and Construction.

Abstract

A detailed experimental and theoretical study of the flow field in the interaction region of a fluidic wall-attachment amplifier was made. Velocity profiles were measured using a laser doppler velocimeter. A mathematical model of the flow was also established, using an integral method. Reasonable agreement between theory and experiments was obtained. As a continuation of previous work, the design of two bistable amplifiers, operating respectively with turbulent and with laminar flow, was optimized. A simplified chemical etching technique was established for the manufacture of such fluidic elements. (Author)
