ABSTRAKT

A technique for approximate calculation of the heat-conduction process in structural elements with thin multilayer coatings has been developed. This technique is based on a substantially simplified solution of the initial problem and is related to modeling of coating by thin-wall shells with relevant geometrical and thermophysical properties of the coating. With such approach, the impact of thin coatings on heat transfer in the system "body-coating" is described by generalized boundary conditions. The efficiency of the proposed approach is illustrated by comparing the results, obtained by its application, with the results of an accurate solution of the test problem − heating of the cylinder with a three-layer coating.
