The flow properties of water and surfactant solutions mixed with counter ions were investigated in flows through small orifices. Good agreement between the resultant pressure drops of water and the numerical predictions of the Navier–Stokes equations was obtained. Compared with those of water, the pressure drops of surfactant solutions were larger for molar concentration ratios of 1.0. Moreover, an...
In vacuum systems gas flows not only through slot channels with constant cross section but also through slot channels with variable cross-section. The relationship obtained analytically for the conductance calculation of three types of slot channels in viscous flow regime at small pressure difference at the ends of the channel is presented in this paper. This relationship is recommended for the calculation...
