摘要：With porous combustor as engineering background, the mass dispersion process of methane and air in highly porous media is studied numerically based on a simplified model for the periodical structure of the porous media. The computational results obtained from the microscopic flow field within a unit cell, i.e., a representative elementary volume, into which a low Reynolds number turbulent model is incorporated, are employed to compute the longitudinal and transverse dispersion coefficients through a volume average approach. The results are compared with experimental data and empirical formulas available in the literature, and a reasonable agreement is achieved.
