Computation of thermal conductivity of compacts in PIM based on fractal characteristic
By analyzing the fractal characteristic of compacts in PIM, algorithm of fractal dimension of its section particle area is presented and anisotropic local area share of section particle in compacts with fractal dimension is counted. Then, based on fiactal model of thermal conductivity in porous media, the anisotropic effective thermal conductivity of compacts and its dimensionless one are calculated, when powder and binder are in series or parallel. Thus, taking Fe compacts for example, the analysis results show that the effective thermal conductivity is enlarger with the increase of fractal dimension.
