Spatial simulation of heat transfer through protective structures in conditions of heterogeneous heat exchange on the boundaries

A spatial nonstationary heat conduction problem has been solved for the region, including protective structures and a protected compartment, given locally concentrated sources of heat release and mixed heat exchange with the environment. A finite difference method and a nonuniform difference grid have been used. The obtained results were used to draw a conclusion on the existence of temperature field nonhomogeneity in the sections passing through the heat-release sources.
