| Outline of Final Research Achievements |
In the study, we measured pressure drops with constant flow rate passing through micro-orifices, which characteristic length was less than 100 micron meters because flow properties of complex fluids in flows through micro-apertures were investigated. For water flows, the experimental results were less than the predicted values of the Navier-Stokes equation. For spherical micelle surfactant solutions (1.0 wt %), different flow properties were found for the various surfactant solutions depending on the charge of the solute. For rod-like micelle surfactant solutions, the resultant pressure drops were larger for molar concentration ratios of 1.0.
