Numerical simulation of time-dependent methane flow
A numerical method of solving the time-dependent gas flow equation with respect to a medium having variable, anisotropic permeability is described. The approximate solutions for this equation are obtained using finite element analysis to give time-dependent gas pressures. A finite element package called pafec'75 was used to facilitate gas pressure distributions, simulation of boreholes and calculation of gas flow for a given boundary. The similarity between the gas flow and the heat flow equation enables gas flow problems to be solved using thermal routines from the pafec'75 program suite, after suitable modifications.
