A review of the models using the Cattaneo and Vernotte hyperbolic heat equation and their experimental validation

Abstract

Abstract Models using Cattaneo and Vernotte hyperbolic heat equation or derived from it (Double Phase Lag model and their various versions) are very common in the present thermal literature, especially for simulating heat transfer at the meso scale, such as in bio heat transfer. Such papers refer to so-called experimental validations made in several previous articles. We show in this short review that the corresponding experiments were biased, because of a deficient methodological approach based on too simple assumptions or on poor data reduction techniques.
