Abstract

In this work, the thermal conductivity problem is solved for fourth layer plate at the heat flux action on one of surfaces. The interfaces between layers are assumed non ideal that leads to appearance of thermal resistances between layers. Additionally thermal resistances are inhomogeneous due to curved surfaces of materials. The existence of curved surfaces and porosity of layers are connected with the way of specimen manufacturing. Thermal conductivity coefficients of layers can by changed when their porosity changes. The problem is solved numerically. It was found that curved interfaces and thermal resistance affect process only at initial stage of the heating. Temperature gradients depend essentially on porosity and thickness of layers.
