Numerical Study on Gas Flow through a Micro-Nano Porous Media

The present research examines the unsteady isothermal flow of a gas through a semi-infinite micro-nano porous medium, a nonlinear boundary value problem on semi-infinite interval. This problem is solved by two different methods and compare their results with solution of other methods is compared. Also through the convergence of these methods, the accurate initial slope y(x) with good capturing the essential behavior of y(x) is obtained.
