项目摘要
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.
本研究的目的是通过实验和模拟阐明高佩克莱数湍流扩散/反应场的拉格朗日多尺度混合机制,并对概率密度函数的数值模型进行验证和发展(PDF ) 方法。为此,我们开发了三维域中速度和浓度三分量的同时测量系统,并利用传统的光吸收光谱法进行了基本反应扩散场的实验。进一步利用随机傅立叶模态法和DNS对反应浓度进行了模拟。从这些实验和模拟的结果中,证实了浓度统计的基本特征,并获得了验证PDF方法数值模型(分子混合模型)有效性的有用数据。
