    Radiant Power Exchange in Thermal Radiation Calorimetry (1998)
    Springer
    International journal of thermophysics 19 (1998), S. 305-315 
    Details
    ISSN: 1572-9567
    Keywords: calorimetry ; emissivity ; heat capacity ; high temperature ; radiant exchange
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Radiant power exchange for thermal radiation calorimetry was investigated both theoretically and experimentally. The geometrical relation in which a disk-shaped copper specimen and a graphite plate are facing each other was used as the model configuration. Surfaces of the specimen and the plate were blackened with colloidal graphite to achieve a high surface emissivity. The radiant power density absorbed by the specimen was calculated by taking into account the geometrical configuration factors and the total emissivity of the blackened surfaces obtained form spectral reflectivity. A value of 0.56±0.01 was obtained for the radiant power exchange coefficient from the theoretical results in the temperature range from 220 to 430°C. The coefficient obtained experimentally by use of a heat capacity measurement was constant with temperature, with a value of 0.54±0.01 within experimental error. No hysteresis in the coefficient was observed for either heating or cooling processes.

    Simultaneous Measurement of Specific Heat Capacity, Thermal Conductivity, and Thermal Diffusivity by Thermal Radiation Calorimetry (1999)
    Springer
    International journal of thermophysics 20 (1999), S. 733-742 
    Details
    ISSN: 1572-9567
    Keywords: calorimetry ; diffusivity ; emissivity, heat capacity ; radiant exchange ; simultaneous measurement ; thermal conductivity
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Thermal radiation calorimetry has been applied to measure the thermal diffusivity of a solid specimen, along with simultaneous measurements of specific heat capacity and thermal conductivity. In this calorimeter, a disk-shaped solid specimen whose surfaces are blackened is heated and cooled slowly on one face by irradiation in a vacuum chamber. A quasi-steady-state approximation in which a linear temperature gradient within the specimen was assumed is considered in the analysis. The validity of this approximation was confirmed by the results of computer simulation based on the control-volume method. Measurements of Pyroceram 9606 and Pyrex 7740 by use of thermocouples in the temperature range between 250 and 400°C gave values consistent with those obtained by previous authors, within experimental error, for all three thermophysical properties.
