The variational form of the mathematical model of a thermal explosion in a solid body with temperature-dependent thermal conductivity
Annotation
The variational form of a mathematical model of a thermal explosion has been developed based on a variational formulation of a nonlinear problem of stationary thermal conductivity in a homogeneous solid body. The model takes the temperature dependence of the thermal conductivity of a solid body into account. The presented example of quantitative analysis of the model demonstrates a method for finding the combination of parameters for determining a thermal explosion in a plate with an exponential temperature dependence of the thermal conductivity. At the same time, the analysis allows one to identify the number of steady-state temperature distributions inside a body whose energy release intensifies with a temperature increase.
