Theoretical and Numerical Characterization of the Thermal Physical Properties of Carbon Ceramic Material

Abstract

The article presents models representative volume element of the porous carbon-ceramic material. Simulating of heat transfer process in a representative volume element is carried out and thermal characteristics of material are determined by a settlement way. Influence of characteristics of material structure – its porosity and type of reinforcement – on values of heat-physical characteristics is investigated. It is shown that in the field of high temperatures (more than 1500 T) the defining role in the course of heat transfer in high-porous (Р> 40%) materials belongs to radiation heat exchange in a pores.
