The process of formation of a temperature field in an 
isotropic solid body containing a spherical heating source with a 
uniformly moving boundary for the case of realization of nonstationary 
heat-exchange regimes that lead to the time dependence of the heat-transfer 
coefficient have been investigated by mathematical-modeling methods.

Keywords: solid body, spherical heating source, mobility 
of the boundary, temperature field, integral transformation.
