Construction of a heterogeneous environment for complex modeling of physical, chemical and dynamic processes on gas-liquid Saturn's moon Enceladus

Abstract: The aim of this work is to design a multiphase, multicomponent, chemically active continuous medium for complex modeling of gas-liquid satellites of the giant planets of the Solar System, i.e. allowing for the integration of various theoretical models into a single whole and taking into account the diversity, mutual influence, and complexity of the numerous physical, chemical, and dynamic phenomena and processes occurring on them. Using nonequilibrium thermodynamics methods, a model of a heterogeneous continuum has been constructed taking into account the asymmetry of the pressure tensor of the phase media, equilibrium chemical reactions, phase transitions, and heat and mass transfer processes.
The developed approach is intended primarily for mathematical modeling of the water ocean and icy shell of Saturn's moon Enceladus, under whose surface one can likely search for extraterrestrial life in the Solar System.

Keywords: methods of multi-velocity mechanics and nonequilibrium thermodynamics, Stefan-Maxwell relations for heterogeneous media, gas-liquid space objects.
