Abstract : DEVICES, Bistable devicesThe report presents a survey of basic flow fields typically found in fluid amplifiers and a summary of five fluid amplifier flow fields. The basic flow fields are presented in terms of the static pressure fields that they produce on bounding surfaces, in the form of lines of constant pressure. Formulas are given that rrquire only a knowledge of the surface pressure and the geometry of the surface to yield quantitative approximations to the velocity fields beneath the surface. Data are also presented in terms of a transition parameter for the transition to turbulence of bounded jets. Knowledge of the basic fields is used in describing the flow fields in five different fluid amplifiers, three bistable and two proportional. (Modified author abstract)
