摘 要：正In this paper an improved finite difference scheme is investigated to solve the equation of filtration type in porous textiles with phase change materials（PCM）,which can be expressed as a nonlinear source term. Due to the effects of source term,the constructed scheme is total variation bounded（TVB）.On the basis of this scheme thermal buffering effect of PCM is *** distributions of the temperature,saturated degree in the porous media with PCM were numerically computed by this *** the comparison the distributions of the temperature,saturated degree in the porous media without PCM were also numerically *** results indicate that this method is satisfactory.
