Abstract

Plate heating with a temperature-dependent absorption coefficient is investigated. It is shown that with increasing power density of an incident flux the kinetics of temperature growth undergoes pronounced qualitative changes. The threshold power density value at which plate heating is accompanied by darkening as well as the darkening time are found. Calculation results are in good agreement with experimental data.
