| 内容記述 | We have developed a micro-mixer based on a free impinging liquid-sheet jet technique. We identified a mixing position where two different solutions mixed uniformly and evaluated a corresponding mixing time in the liquid-sheet jets with homogeneous combination (H2O and H2O) and heterogeneous combination (C2H5OH and H2O). By observing a quenching reaction, the mixing times were evaluated to be 36 μs for the homogeneous combination (H2O/H2O), and 46 μs for the heterogeneous combination (C2H5OH/H2O). To clarify the mixing mechanism in the liquid-sheet jet, the theoretical mixing times were calculated by two different models assuming laminar and turbulence flows. The calculated mixing times based on energy dissipation in the turbulence flow are in great agreement with the observed mixing times for both H2O/H2O and C2H5OH/H2O combinations. These results indicate that turbulent mixing is a dominant mixing mechanism in the liquid-sheet jet, and that no clear interface is formed between H2O solutions and between C2H5OH and H2O solutions. The liquid-sheet jet technique provides a windowless and ultra-thin target and would be useful to investigate intermediates in mixing-driven chemical reactions such as an oxidation in solution and a folding reaction of proteins proceeding in a microsecond time scale. | |||||||||
