Outline of Final Research Achievements |
We have established the basis of innovative measurement technologies for fluid mechanics by integrating interdisciplinary sciences of advanced optical science, optical micro fabrication and CFD. On the basis of experimental results of nonlinear interaction between femto-second laser pulses and transparent materials (quartz and ultra-pure water) by using femto-second-order time-resolved measurement, we developed novel technologies of micro-fabricating quartz optical fiber. Furthermore, we developed a new method to three-dimensionally simulate propagation of laser beams in the optics and a measurement target, in consideration of gas-liquid interfaces, reflection, refraction, polarization and ray energy. Integrating the above, we have created multifunctional optical fiber probes. In addition, we applied the new OFP to measurement of droplets/bubbles in a GTL process, and to measurement of foams generated in a decontamination process.
