| Outline of Final Research Achievements |
The concentration measurement system of multiple species by the light absorption spectrometric method has been developed to clarify characteristics of turbulent reactive flows in liquid, which is characterized by a high Schmidt number. The validity of this system is confirmed by a simultaneous measurement of concentrations of three species in a turbulent jet.
Furthermore, the modeling of turbulent reactive flows is conducted by the probability density function (PDF) method as a stochastic model. The numerical simulation of reactive diffusion field in liquid grid-turbulence is performed, and a validity of simulation is ascertained.
