OF HEATING AND ENTRAINMENT OF MASS OF A MATERIAL

A model of heating and thermal destruction of a material 
is suggested on the basis of analysis and generalization of 
computational-experimental and literature data. The fundamental 
importance of the constant of thermal destruction in nonstationary 
processes of heating and entrainment of mass and its interrelation 
with the heat of material evaporation are shown. The mechanism 
of heat absorption in the surface layer of the destructing material, 
which determines the time of reaching the quasistationary mode of 
heating and entrainment of mass, is found. The limiting power 
capacity of internal and surface processes of heat absorption by 
a heat-protective material is considered.
