Simulation of radiative transfer in dispersive multiphase systems with supercritical fluidic components

An algorithm for modeling light transfer within a complex two-phase foam-like structure using the Monte Carlo simulations is presented. At different stages of aging, gas bubbles in the foam-like medium were presented as Kelvin cells. A tree-dimensional structure was considered as a system of closely packed ordered tetradecahedrons, which are similar in shape to the truncated octahedra with a slight rounding of the walls to satisfy the Plateau rule. The spherical shape of the cells describes the gas bubbles at the early stages, when the foam is wet. In contrast, the polyhedron shape describes the gas bubbles when the foam is dry. Transmittance coefficients of a two-phase foam-like medium for the various radii of the gas bubbles are calculated using the Monte Carlo modeling. Development of such theoretical approach to diagnose the foam structure diagnostic allows for the optimization of synthesis of highly porous materials with the required properties, particularly applying the gas-based and supercritical techniques. This study can be useful for the development of biomedical technologies, especially for the tasks of synthesizing cellular scaffolds.
