| Abstract: | This study simulates the effects of different temperature pulse inlet conditions on non Fourier heat conduction problem, and numerically predicts different non Fourier heat conduction characters produced by different pulse types and different pulse frequencies, respectively. Also, the differences between thermal wave, non Fourier and Fourier heat conduction under the same pulse condition are showed. |

| Keywords: | non-Fourier heat conduction DPL model temperature pulse thermal accumulation dissipation effect |
