Engineering Physics Annotation << Back The Unsteady Process of Heat Propagation in the Final Rod Kanareykin A.I. The article is devoted to the issues of non-stationary thermal conductivity in a rod. The problem differs from solved similar problems in that the problems were solved for the case of an infi nite rod. This is also the case of a fi nite rod, so it is necessary to take into account the boundary conditions at the end ends of the rod. When fi nding a solution, the series decomposition method is used. The main statements in the paper are proved using Dirichlet and Riemann-Lebesgue lemmas. The paper also considered a special case when the ends of the rod are maintained at constant temperatures. Keywords: heat transfer, rod, boundary conditions, initial conditions, thermal conductivity, series, Dirichlet lemma, RiemannLebesgue lemma. Pp. 37-42.
