| Outline of Final Research Achievements |
Specific microfluidic flows with two-phase separation mixed solvent solutions, such as ternary water-hydrophilic/hydrophobic organic solvent, water-surfactant, water-ionic liquid, and fluorocarbon/hydrocarbon organic solvent mixtures, have been reported as a new type of multiphase flow. When homogeneous mixed solvent solutions are fed into a microspace, the solutions change from homogeneous to heterogeneous solutions featuring a liquid-liquid interface via phase transformation by changing the pressure and/or temperature. This type of flow is called “phase separation multiphase flow” (PS-MPF) and differs from conventional immiscible multiphase flows. In particular, the annular flow in a PS-MPF is interesting and useful. This flow is called a “tube radial distribution flow” (TRDF). The outline of the PS-MPF has been clarified from various viewpoints of the first research stage. New technologies were developed based on a TRDF in a PS-MPF.
