Abstract

Abstract:

By using the developed numerical method, w hich combines the dual reciproci ty boundary element method (DRBEM)with Laplace transform and inverse transform, a kind of non-Fourier heat conduction problem under iso thermal inlet condi tion is numerically simulated.The dif ferent characters fo r thermal ware heat conduct ion, non-Fourier heat conduct ion and Fourier diffusion is presented, the obvious difference between their marching velocities of the temperature f ront is found.
