MODEL OF ITS DESTRUCTION

The results of a numerical solution of the equations constructed 
for a frozen boundary layer on the surface of a carbon material, with 
allowance for the complete thermochemical model of the entrainment 
of its mass, are presented. The results obtained are compared with 
the data that correspond to the use of the analogy between the processes 
of heat and mass transfer in a boundary layer and of the simplified 
model of the mass entrainment of the materials of the class considered. 
The results of comparison between experimental and calculated-theoretical 
data on the rate of destruction of the ATJ-grade graphite are also 
presented.

Keywords:  graphite, oxidation, sublimation, evaporation, 
condensation, diffusion, mass entrainment, boundary layer.
