The work consists of an abstract, 3 chapters, a conclusion, a list of literary sources used in the work, applications. The total volume of work is 83 pages, including the main part - 77 pages. The work contains 8 tables, 13 figures, 50 references to used literary sources. The object of research is non-stationary thermal processes in multilayer structures of basic geometric shapes under fire conditions. Research methods - To achieve this goal and solve the problems of theoretical research, methods of mathematical modeling, the main provisions of the theory of heat transfer, equations of mathematical physics, non-stationary heat conduction, the foundations of the theory of generalized quasi-differential equations were used. Theoretical studies were carried out using mathematical modeling and other analytical methods. In solving problems, experimental and analytical methods are effectively used, which provide for measuring the temperature and density of the heat flux with the help of appropriate instruments before decoupling the corresponding boundary value problem. When calculating the corresponding specific problems, computer technology and the Maple 13 programming language were actively used. Results - in a closed form, the decoupling of the non-stationary heat conduction problem for multilayer flat structures of basic geometric shapes under the boundary conditions of heat transfer of the third kind was obtained, further makes it possible to study fire resistance (by the ability) of building structures under fire conditions, flows at nominal temperature conditions. The direct method for calculating temperature fields in multilayer structures of basic geometric shapes can be used to study non-stationary thermal processes without the use of approximate and operational methods.  Product Description popup.authors Pazen Oleg Yu Stasiuk Marta F Tatsii Roman M popup.nrat_date 2021-01-11 Close
