Abstract: |
We study the behavior of the solution to the full compressible Navier-Stokes fluid in porous medium. By using standard energy and two-scale convergence, we prove the strong convergence of the density and the temperature with characteristic size of the pores ε in Rn for n = 2 or 3 and obtain the homogenized for this model, when ε→0, which gives another explanation to the results in references. |
