| 英文摘要 | The permeability identification problem for two-dimensional porous medium was studied by both the direct and the optimization method in this paper. The formulation is different from the usual ones. The permeability is determined from the arrival-time at every point in the fluid, which can be measured by experiments. This inverse problem can be solved in two steps,and consequently divided in two subproblems to research. First, numerical algorithm of velocity inversion for two-dimensional porous medium will be studied from the arrival-time of the fluid, followed by the study of numerical algorithm of permeability inversion for two-dimensional porous medium from velocity. Finally numerical examples will be given. Numerical results indicate effectiveness and validity of the numerical algorithm. |
