EXPERIMENTAL STUDY ON THE INFLUENCE OF FREEZING TEMPERATURE AND FREEZING WATER'S ELECTRIC CONDUCTIVITY ON THERMAL CONDUCTIVITY OF ICE

摘要

The freezing temperature and freezing water's electric conductivity are different in icing events occur at different areas and different time. But there is little research about the effect of freezing temperature and freezing water's electric conductivity on the thermal conductivity of ice. The paper experimentally studies the effect of freezing temperature and freezing water's electric conductivity on thermal conductivity of ice, based on the transient hot probe method. The result show that the thermal conductivity of ice increases and decreases with the decrease of freezing temperature and increase of freezing water's electric conductivity; the higher the freezing temperature is, the greater influence of freezing water's electric conductivity on thermal conductivity is; the glaze in nature is greatly influenced by freezing water's electric conductivity.
