The Model of Radiation-Induced Heat Flow in Heterogeneous Porous Materials

The paper is devoted to the description of a complex approach to the numerical modeling of secondary thermodynamic effects generated in heterogeneous porous-type materials under the influence of ionizing radiation. This approach is divided into several stages including the construction of a geometrical model of a porous material, simulation of interaction with radiation and further modeling of thermodynamic effects. The creation of a geometric model occurs in accordance with a number of requirements put forward by the general approach. To simulate pores distribution, Lubachevsky Stillinger spheres packing algorithm is used. The approach also includes the algorithm for construction of system of detectors for statistical estimation of the radiation energy deposit in an irradiated object. The distribution of energy release in an irradiated sample obtained at the second stage of numerical simulation is used in hydro- and thermodynamic models to estimate the secondary thermodynamic effects. Thermodynamic behavior of corresponding material is described using the hydrodynamic model.
