Численное моделирование трехмерных нестационарных процессов теплопроводности в неоднородных телах

Numerical modelling is a powerful tool for the study of such processes, allowing to take into account complex geometry, inhomogeneity of properties and non-stationary nature of thermal fields. Modern computational methods provide high accuracy and stability of solutions even for complex three-dimensional problems. The relevance of the study of three-dimensional unsteady heat conduction processes in inhomogeneous bodies is due to the need to optimise thermal regimes in technical systems, improve the efficiency of heat exchange and ensure the reliability of structures. In this article the main approaches to numerical modelling of three-dimensional non-stationary heat conduction processes in inhomogeneous bodies are considered. An inhomogeneous structure with a cube-shaped cavity or an insulated copper inclusion in its centre is studied, and the influence of inhomogeneities on the temperature field distribution is investigated.
