| Abstract |
| he study of nonlinear heat wave propagation in rigid thermal conductors is an important topic in the field of heat transfer and thermal physics. Classical heat conduction theories, based on Fourier’s law, predict an infinite speed of heat propagation, which is inconsistent with experimental evidence. To address this limitation, generalized theories have been developed that describe thermal waves with finite speed, often referred to as second sound. This work explores the mechanisms of nonlinear heat wave propagation in rigid conductors, emphasizing the influence of nonlinearity and material properties on wave speed, dispersion, and attenuation. The study highlights the significance of considering non-Fourier effects to achieve a more realistic understanding of heat transport at micro- and nano-scales, as well as under extreme thermal conditions. The results contribute to a deeper insight into the fundamental nature of thermal wave phenomena and provide a theoretical foundation for future applications in advanced materials, thermal management, and engineering technologies. |
