Investigation of Effective Thermal Conductivity of Porous Materials 2005-01-3029

An experimental steady state method and test apparatus were developed to measure the effective thermal conductivity of porous materials in the temperature range of T ≈ 600–2000K at environmental gas media pressures ranging from 100 to 105kPa.
The investigation of heat transfer and effective thermal conductivity of two high porous molybdenum cellular materials (material No 1 with density ρ = 800 kg/m3 and material No 2 with ρ = 300 kg/m3) were performed in a temperature range of T ≈ 600–2000K under vacuum and ambient pressure conditions.
The overall measurements uncertainties were assessed to be less than 6.5 %.
