Measurement of Thermal Conductivity of Ice Slurry made from Solution by Transient Line Heat Source Technique (Analytical Discussion on Influence of Latent Heat of Fusion of Ice)

摘要

When a thermal conductivity of ice slurry made from a solution is measured by a transient line heat source technique, a measurement value is affected by a latent heat of fusion of ice. Therefore, the thermal conductivity measured is an apparent thermal conductivity. In this study, influence of Stefan number, initial concentration of the solution, initial solid fraction and Fourier number on the thermal conductivity was analytically discussed to improve measurement accuracy of the thermal conductivity of ice slurry in the case using the transient line heat source technique.
