Semi-analytical method for thermal calculation of the multilayer cylindrical rods with internal heat generation

An approximated method for calculating the temperature field in multilayer rod cross sections with internal heat generation is suggested. For the solution of the problem the Fourier finite series method has been used. The method is intended for calculating temperature stationary field in cross sections of rods with arbitrary number of layers (from 2 to 10 layers) which can be located tightly or with gaps. There can be ideal thermal contact or exist thermal resistance between layers. It is advisable to use algorihm for the solution of optimization problems. The method ensures high accuracy of the calculation
