ON ONE METHOD OF SOLVING NONSTATIONARY HEAT-CONDUCTION PROBLEMS FOR MULTILAYER STRUCTURES
V. A. Kudinov, V. V. Dikop, S. A. Nazarenko, and E. V. Stefanyuk UDC 536.2 As applied to the solution of the heat-conduction problem for a two-layer structure, the Fourier method is used jointly with the orthogonal Bubnov-Galerkin method. An important feature is the introduction of additional boundary conditions, the need for which is explained by the appearance of an additional parameterafter the separation of the variables in the input differential equation. The additional boundary conditions are derived from the basic differential equation by differentiating it at the boundary points.
