Abstract: The paper presents chosen experimental and model methods of investigating heat transfer in a steel porous charge. The results of this investigation provide information on both the qualitative and quantitative course of the analysed processes of heat exchange. The parameters which characterise the analysed phenomenon in a quantitative manner, among others, are: The effective thermal conductivity k ef , the thermal contact resistance R ct and Nusselt number Nu . It has been established that it is not possible to use literature models in order to determine the k ef coefficient. The authors present their own model of effective thermal conductivity. The above-mentioned parameters for a porous charge reach the values within the following ranges: k ef : 1.0–8.5 W/(m·K); R ct : 0.0019–0.0057 (m 2 ⋅K)/W; Nu : 1.2–7.1.
