Abstract
Percolation theory is widely used to study heat transfer and other kinetic processes in systems with disordered structures. This paper proposes a phenomenological approach combining methods of percolation theory and multifractal analysis to model a percolation cluster in a three-dimensional infinite medium with multifractal properties. Based on the developed model, unambiguous numerical values for topological critical indices and the critical conductivity index were obtained, previously unknown relationships between critical indices were revealed, threshold conditions that separate qualitatively different regimes of system behavior in the scales of correlation length were determined, and a relationship between the systems order parameter and the golden ratio was established, which indicates the universal nature of the identified dependences.
