Accuracy of the switching pressure of fluidic amplifiers
Abstract
Statistical properties of the switching process of wallattachment amplifiers are studied to clarify the accuracy of the switching pressure. The switching process is classified into two modes: initial switching and random switching. The probability distribution functions of the switching delay are determined for both switching processes by considering the average deflection and random fluctuation of the attached jet. A mathematical model is verified experimentally, and the model parameters determined. The relation between input pressure and switching probability for an input pulse of finite duration is obtained by the mathematical model. A longer pulse yields a smaller pressure range of uncertain switching. The theoretical estimate is verified experimentally.
