Results of the modeling of the process of heat transfer 
from a circular tube filled with granular bed with boundary conditions 
of the first, second, and third kind have been presented. The physical 
characteristics of the wall zone and the relative value of its thermal 
resistance have been determined based on an analysis of experimental 
data on the nonstationary heat exchange of the unblown granular bed. 
Recommendations on calculation of the heat exchange at elevated temperatures 
have been given.
