AND NONSTATIONARY BOUNDARIES

A numerical-analytical solution of a differential 
heat-conduction equation is suggested. Analytical expressions relating 
the initial and boundary conditions of heat transfer to parabolic 
temperature distributions in the layers of the cylinder are obtained 
for the end of the calculated interval of time. The calculation of 
the temperature field is reduced to the solution of a system of two 
ordinary differential equations. The error of the solution is analyzed.
