Growing interfaces in quenched disordered media
We present the microscopic equation of growing interface with quenched noise for the Tang and Leschhorn model [Phys. Rev. A 45, R8309 (1992)]. The evolution equations for the mean heigth and the roughness are reached in a simple way. Also, an equation for the interface activity density (i.e. interface density of free sites) as function of time is obtained. The microscopic equation allows us to ...

An equation for the interface activity density (or free sites density) as function of time is obtained. The microscopic eq...
متن کاملA Review of Growing Interfaces in Quenched Disordered Media
We make a review of the two principal models that allows to explain the imbibition of fluid in porous media. These models, that belong to the directed percolation depinning (DPD) universality class, where introduced simultaneously by the Tang and Leschhorn [Phys. Rev A 45, R8309 (1992)] and Buldyrev et al. [Phys. Rev. A 45, R8313 (1992)] and reviewed by Braunstein et al. [J. Phys. A 32, 1801 (1...
