Abstract
A new method and software for numerical solution of inverse coefficient problems of nonlinear heat and mass transfer in anisotropic heat-protective materials for flying vehicles subjected to aero- and gas dynamics heating. The nonlinear components of heat conductivity tensor are main high-temperature properties of anisotropic heat-protective materials. These components must be reconstructed using the temperature measurements in the nodes of the space-time net. The proposed method is based on the new absolutely stable method of variable directions with extrapolation of numerical solution for heat transfer problems and parametric identification. Some results of heat conductivity tensor’s recovery have been obtained for carbon-carbonic composite material and based on nonlinear heat conductivity experimental investigation.Keywords:
