Analysis of heterogeneous Markov media for particle transport problems
Autor: Mikolaj Adam Kowalski, Coline Larmier, Andrea Zoia
Publikováno v: Physical Review E. 106
Markov media provide a prototype class of stochastic geometries that are widely used in order to model several complex and disordered systems encompassing, e.g., turbulent fluids and plasma, atmospheric layers, or biological tissues, especially in re

In a recent article, Krapivsky and Redner (J. Stat. Mech. 093208 (2018)) established that the distribution of the first hitting times for a diffusing particle subject to hitting an absorber is independent of the direction of the external flow field.

Publikováno v: EPJ Web of Conferences, Vol 247, p 04009 (2021)
Random media emerge in several applications in reactor physics and safety analysis. Most often, models of stochastic media assume spatial homogeneity, whereas real-world complex materials, such as fuel chunks resulting from core degradation, typicall
