Корректировка осесимметричных

задачи теплопроводности |
Огородникова В.В., Огородников И.Н.
Thermophysical properties of materials, expressed as tabular functions of temperature, represent
the coefficients of the nonlinear heat conduction equation and are essential input data for computer
simulation of high-temperature processes. This article presents the results of developing algorithmic and
software tools for determining the thermophysical properties of non-metallic materials for an inverse
coefficient heat conduction problem. The developed software consists of two modules implemented in the
SciLab environment. The main module considers thermal conductivity to restore the thermal conductivity
coefficient in various temperature ranges, using a genetic method and an optimization method with
a quadratic approximation of the cutoff function, iterating through the other module. The additional
module defi nes the heat conduction problem, calculates the transient temperature field in a cylindrical
coordinate system, and uses finite difference methods to streamline the calculation time compared to a
commercial program.
Keywords: inverse coefficient heat conduction problem, simulation, axisymmetric model.
