Fluidic Logic Element Performance Calculation

The results of gas-dynamic characteristic studies of logic chips jet element are considered. The study carried out by numerical method is based on the integration of the Navier–Stokes equations. For closure of simultaneous equations in this research, the two-region hybrid turbulence model of transfer of tangential stress is used. The model of compressed viscous gas is applied. Its properties correspond to properties of air of standard atmosphere at the height of mean sea level. The main characteristics of the switching logic element output signals, depending on the influence of control signals, were found. It is shown that relative rate in the output channels depends on the relative pressure in the control channels. It is calculated the required values of pressure in control channels of logic element necessary for switching of an output signal. Because of viscous properties of working body, the Coanda effect which is used for sticking of feeding air current to channel walls for purpose of steady work logical device is realized. Zones of flow contraction are installed in channels of device
