The thermal diffusivity of ice and water between -40 and + 60° C

Abstract

The thermal diffusivity αs of triply-distilled deionised water, and αL of single-crystal ice along the c-axis, have been measured by Angström's method. The temperature range covered was -40 to +60° C. The results for water compare well with published data for the thermal conductivity, but for ice there are unexplained discrepancies. The linear relationships αs=(8.43-0.101 T) 10-3 cm2/sec and αL=(1.35+0.002 T) 10-3 cm2/sec where T° C is the temperature, fit the data obtained. © 1968 Chapman and Hall.
