Abstract Special flow mechanism and percolation characteristics for gas transport are presented in nanoporous media, which cannot be explained by the traditional motion equation of Darcy's law. On the basis of theoretical analysis, we establish a low velocity nonlinear transfer equation of gas in nanoporous media and a mathematical model of gas volume flow in multi-scale porous media. By utilizing nonlinear numerical calculation methodology, a detailed quantitative analysis of the diffusion and convective rate of gas flow is presented, providing a theoretical foundation for the development of nanoporous media.
