Abstract
A layer of composite material is investigated, which is heated one-sidedly with one-dimensional energy transfer accounting for thermal conductivity and radiation. A mathematical model is suggested for non-stationary coefficient thermophysical problem under radiative-conductive heat transfer in a material layer. Temperature dependencies of thermal capacity and thermal conductivity coefficient of composite radio-transparent material have been determined through numerical modeling by solving the coefficient reverse problem of thermal conductivity.
Highlights
Composite radio-transparent materials are widely utilized as protection devices for aircraft antennas [1, 2]
When solving thermal conductivity problems, first, second- or third-type boundary conditions may be used in arbitrary combinations for each of the surfaces
The diversity of boundary condition types allows modeling arbitrary heat response conditions and processing the experiment results, which have been conducted on installations varying in design and sample heating conditions [8, 9]
