The aim of this paper is to model thermal flux versus temperature in an aluminum rod. The objective is to check whether a theoretical model applies to experimental data and then to investigate some more effective fractional models from black box identification. For this particular system, it is shown that fractional models are more suitable than rational ones, since they require fewer parameters to achieve the same quality of approximation.
