An Experimental Study of the Switching Dynamics of Monostable Fluid Amplifiers.
Abstract
The transient switching times of monostable fluid amplifiers were determined experimentally using a large model with a power nozzle width W of 3/4 in. Straight and convex attachment walls of equal length were tested. Water was used as the fluid and the flow field was made visible by generating hydrogen bubbles at the power nozzle exit. Three different Reynolds numbers based on W were used. The control slow was applied as a step, starting from an initial value of zero. Effects of attachment wall shape, opposite wall setback, control flow, load changes on the active output leg, Reynolds number and splitter position on the transient switching times were studied. It was desired to know whether the convex attachment wall provided better switching characteristics than the straight attachment wall.
