On the two-temperature description of heterogeneous materials

The thermal behaviour is critical in numerous applications, affecting any device’s lifetime and safe operations. Adding that the technological development resulted appearance of complex material structures, making research on advanced models even more important. Materials like 3D printed foams, or with a biological origin often show non-Fourier response. Modelling such problem requires thorough analysis deep understanding models. present paper focuses two models, called two-temperature Guyer-Krumhansl equations. We compare their physical background characteristic behaviour. Additionally, we perform first experimental test model. It found solutions model deviate from ones predicted by equation. However, both approaches can data under certain conditions offer different insights about observed heat conduction phenomenon.
