    Notes: Abstract A novel device for measurements of the normal and directional total emissivity of solid surfaces in the range 300–600 K is described. The measurements were performed using the radiation comparison method. A novel black-body radiation source is used as a standard. The detection system consists of a pyroelectric head, a preamplifier, a chopper, and a matching lock-in amplifier with analog recorder ourput. The device is simple and well suited for routine measurements. Comparison of our results with those of previous investigations shows a good agreement.

    A Method of Determining the Thermophysical Properties and Calorific Intensity of the Organ or Tissue of a Living Body (2000)
    Springer
    International journal of thermophysics 21 (2000), S. 207-215 
    Details
    ISSN: 1572-9567
    Keywords: calorific intensity ; hot probe ; organ or tissue of a living body ; specific heat ; thermal conductivity ; thermal diffusivity

    Topics: Physics
    Notes: Abstract A new method was developed to determine simultaneously the thermal conductivity, thermal diffusivity, specific heat, and calorific intensity of the organ or tissue of a living body either in vivo or in vitro with a thin hot probe. By using the method, the thermophysical properties and calorific intensities of a human palm and in vivo liver and a kidney, heart, brain, and foreleg and hindleg muscles of an anesthetized canine were measured. It is concluded that there are no significant differences in the thermophysical properties of organ or tissue of a living body either in vivo or in vitro. The measured thermophysical properties are in good agreement with those reported in the literature.

    An Improvement on the Prediction of Optical Constants and Radiative Properties by Introducing an Expression for the Damping Frequency in Drude Model (2000)
    Springer
    International journal of thermophysics 21 (2000), S. 269-280

    ISSN: 1572-9567
    Keywords: aluminum ; copper ; damping frequency ; Drude model ; optical properties ; radiative properties

    Topics: Physics
    Notes: Abstract A method for predicting the optical constants and the radiative properties of metals and heat mirror films, by introducing an expression for the damping frequency in the Drude model, is described. The directional emissivity of aluminum predicted by this method agrees well with the classical experimental values given by Schmidt and Eckert. The prediction of the normal emissivity of indium–tin–oxide (ITO) heat mirror films is in agreement with our measured results. The directional emissivity of copper predicted using this method is reported. The calculated result of the spectrum normal emissivity of copper at 4 μm and 20°C is also given, which supports the measured result. The values for the directional emissivity of aluminum calculated by using various methods based on the Hagen–Rubens relation are reported, and the values do not agree with the experimental results.
