説明
<p>This paper proposes a unified model that includes an effect of preferential diffusion of hydrogen. As hydrogen has a larger diffusion coefficient than methane and oxygen, the mass fraction of hydrogen varies in a premixed flame which is with curvature. This phenomenon is well known as preferential diffusion of hydrogen. Kido and Nakahara reported that the preferential diffusion influences the blow off limit of turbulent premixed flame and estimated the empirical formula due to experimental data. To simulate combustion phenomena of premixed gas that includes hydrogen with high accuracy, the preferential diffusion should be considered on the combustion model. On this paper, a simple model of the diffusion process of fuel in the premixed gas was evaluated firstly. Next, the results were applied to the author's combustion model. The results were compared with the experimental data by Kido and Nakahara and were in good agreement.</p>
