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.
