Abstract:

A two-dimensional, incompressible model is examined for the response of lamina and turbulent attached jets to arbitrary control pressures applied to either or both control ports of a flueric bistable amplifier. Effects of the nonlinear, lumped-parameter, inductive and resistive supply, control, vent, and output lines, and effects of the wall opposite the attachment wall are considered. All geometric parameters such as wall angle and offset, vent location, line size, and nozzle width may be varied. Switching time data for seven different geometries and steady-state attachment-point data for both closed and open control ports, as well as the response of an actual amplifier compare favorable with analytical predictins. The response of a laminar jet to a ramp input pressure change is also given. The analytical results are in good agreement with experimental data. These results indicate that the analytical model is valid and that it can be used as a basis in designing future flueric amplifiers.
