Abstract

In this paper, a method of parametric identification of the radiation-optical characteristics of the surface of the screen – vacuum insulation is considered based on the results of thermal vacuum tests of a sample in the form of a paralepiped. The method is based on minimizing the root-mean-square error between the theoretical and experimental temperature field in the places where temperature sensors are installed. The minimization problem is solved by the gradient method of conjugate directions.

Keywords:

screen-vacuum thermal insulation, iterative regularization method, conjugate directions method, thermal conductivity equation
