Abstract: | In this work, the heat transfer phenomena taking place during the cooling of thin films of crystallizable polymers were analyzed.
The thermal histories, as recorded during experimental cooling runs carried out at various cooling rates, were compared with
the predictions of a general purpose numerical code, which was resulted able to capture all the main features of the process.
Thus, the conditions which allow homogeneous cooling (negligible temperature gradient within the sample) or homogeneous cooling
history (the same cooling history for all the positions within the sample) were predicted by the simulation code. |
