| Abstract: | The property of reactive flows in porous media was discussed. With the help of perturbation method of inner and outer solution, the linear relation between the change of normal velocity, normal gradient, gradient of diffusion, gradient of infiltration and curvature and the change of concentration, the pressure induced by the change of porosity were all analyzed. The diffusion equation describing central boundary was thus obtained in theoretical method. |
