| Research Abstract |
The purpose of this study is to elucidate the Lagrangian multi-scale mixing mechanism of the high-Peclet number turbulent diffusion/reactive fields by the experiments and thesimulations, and to make the verification and development of the numerical models for the probability density function (PDF) method. For this purpose, we develop the simultaneous measurement system of three components of velocity and concentration in a three-dimensional domain, and also perform the experiments for the fundamental reactive diffusion field by the conventional light absorption spectrometric method. Further, the simulations of reactive concentration filed by the random Fourier modes method and DNS are performed. From these results of experiments and simulations, the fundamental characteristics of concentration statistics have been confirmed and the useful data for the verification of the effectiveness of the numerical model (molecular mixing model) for the PDF method have been obtained.
