摘要

In this paper, we consider a computational model for a mixed nonlinear heat equation with boundary conditions of the third kind that describes the process of switching off an electric arc including the interval of its stable combustion until the moment of switching off and replacing the strictly hyperbolic heat equation with a hyperbolic-parabolic equation. The numerical simulation of this problem based on an implicit difference scheme and the heat balance method was performed by using the MathCad-15 software. Also, we prove the well-posedness of the first boundary-value problem for some high-order nonlinear equation.
