Abstracts
Mixed wet percolation I: Geometrical Properties
Prof. Dr. Sitangshu Bikas Santra
Inspired by recent work on immiscible two-phase flow in mixed wet porous media, we study a system undergoing a percolation transition of the perimeters of a site percolation problem in this paper. The geometrical properties at the criticality of the perimeter system are numerically measured, and their scaling relations with the respective density parameters are studied. We also verified their finite-size scaling relations. Though the site clusters and their perimeters look very different, the singular behaviour of the associated geometrical properties remains unchanged. The geometrical critical exponents are found to be those of the ordinary percolation. Finally, we justify why the two different systems are in the same universality class.
Mixed wet percolation II: Transport Properties
Jnana Ranjan Das
Inspired by recent work on immiscible two-phase flow in mixed wet porous media, we study the transport properties of the perimeters network of a site percolation problem. The exponents of higher order moments of the current distribution and dimension of back bone are measured.
