| Abstract: | The experimental research on the apparent conductivity of pearlite in different particle sizes and different vacuity is reported. The model of conduction and radiation heat transfer in vacuum pellet materials is used and its numerical solution is given. This paper presents a method by which the experimental result can be extrapolated to other situation. |
