Comparing the dual phase lag, Cattaneo-Vernotte and Fourier heat conduction models using modal analysis
作者：
Highlights：
• Dual phase lag, Cattaneo-Vernotte and Fourier heat conduction models are compared.
• Modal analysis provides realistic values for lag times of DPL and CV models.
• Approximate series solutions converge in terms of an energy norm which is stronger than the maximum norm.
• Heat pulse progresses slower into specimen for DPL and CV models than for Fourier model.
• Vibrational analysis provides insight into series solutions of DPL and CV models.
