Methods of representing parameters in fluidic elements and their equivalent circuits have not been developed except the method used for the small amplitude equivalent circuits of analog elements.
In this paper, a method of representing parameters of analog and digital fluidic devices is presented, by using the linear relationship between the pressure drop and the squared value of the flow in the output characteristics. An equivalent pressure source and a nonlinear resistance are used to indicate the characteristics of each device, and are very convenient for the representation of parameters when the device uses the turbulent jet and is furnished with the vent around the receiving port.
This method of representation proposed enables us:
(1) to evaluate the characteristics of the elements,
(2) to calculate the pressures and flows in the circuits, and
(3) to measure the figures of merit in designing the elements.
