| Abstract: | By using the developed numerical method, which combines the dual reciprocity boundary element method (DRBEM) with Laplace transform and inverse transform, a kind of non-Fourier heat conduction problem under isothermal inlet condition is numerically simulated. The different characters for thermal ware heat conduction, non-Fourier heat conduction and Fourier diffusion is presented, the obvious difference between their marching velocities of the temperature front is found. |

| Keywords: | non-Fourier heat conduction Dual-Phase Lag model characters of the temperature field marching velocity of the temperature front |
