Abstract

This paper solves the problem of the identification of a complex of heterogeneous, thermophysical properties that are part of a system of ordinary differential equations of a mathematical model with lumped parameters. The previously developed iterative-variational method is used to regularize an unstable solution of the inverse heat-transfer problem. The results confirm the efficiency of this regularization method and make it possible to study the temperature dependences of the emissivity and thermal resistance of screen-vacuum thermal insulation.

具有集总参数的传热数学模型中筛真空绝热的发射率和热阻的识别

摘要

本文解决了识别具有均质参数的数学模型的常微分方程组的一部分的复杂，非均质，热物理性质的问题。先前开发的迭代-变分方法用于规范逆传热问题的不稳定解。结果证实了这种正则化方法的有效性，并有可能研究屏蔽真空隔热材料的发射率和热阻的温度依赖性。
