Measurements on anisotropy of thermal conductivity of ice
Landauer, J. K. (Joseph K.); Plumb, H.
Research ReportA comparison technique is used to measure the anisotropy in the thermal conductivity of ice. Samples of laboratory-grown monocrystals, glacial monocrystals and polycrystalline commercial ice were studied. No effects due to the grain boundaries are observed. The experiments indicate that the conductivity in the direction of the c-axis may be about 5% greater than normal to it. The probable error in the results is about 2%. Analysis of the data leads to the conclusion that, if a difference in conductivity exists, it is less than 8%. More accurate experimentation is necessary to specify the anisotropy with greater precision.
