ABSTRACT
In unsteady-state heat transfer, one must take into account the heat capacity of the solid material. Here, we take up the problem of the solid walls by a periodic method which gives without simplification the heat transfer across the wall in a form that is very easy to use. Then we only need a spacial partition. In case of a step input, the step responses are well obtained by sommation of a Fourier series.
