INVESTIGATION OF THERMAL RESONANCE IN SOLUTION OF A TWO-DIMENSIONAL SINGULARLY PERTURBED BOUNDARY-VALUE PROBLEM OF NONSTATIONARY HEAT CONDUCTION WITH NONLINEAR BOUNDARY CONDITIONS OF THE STEFAN-BOLTZMANN TYPE
A. V. Kotovich and G. A. Nesenenko UDC 536.2 Data of the analytical-numerical parametric investigation of a singularly perturbed temperature field in the boundary layer of the side of a rectangle on which nonlinear boundary conditions of the Stefan-Boltzmann type are specified have been given. It has been established that a nonuniform initial temperature distribution of the Gaussian type causes the appearance of "discontinuous traveling thermal waves" in the corresponding boundary layer. A set of parameters for which the "discontinuous traveling thermal waves," being superimposed, lead to a local nonlinear enhancement of the thermal field has been found. This effect can be considered as "thermal resonance." N. E. Bauman Moscow State Technical University, 52nd Baumanskaya Str., Moscow, 105005, Russia; email: fn2@sm.bmstu.ru.
