雨凇冰层热导率影响因素的试验分析
Experimental Analysis on the Influence Factors of Ice＇s Thermal Conductivity
摘要
Abstract
The thermal conductivity of ice is the basis to predict accretionj to choose reasonable lce-memng current and to predict the ice-melting time. Consequently, the thermal conductivity of ice is selected from empirical equa- tions given by Abels, Jason, Devaux and Yoshida when the ice density is low, and it is selected as the pure iceI s thermal conductivity when the ice density is higher. The freezing temperature and freezing Water＇ s electric conduc- tivity are different in icing events occurring at different areas and different time. We experimentally studied the effect of freezing temperature and freezing water＇s electric conductivity on thermal conductivity of ice, on the basis of the transient hot probe method. The results 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 tem- perature is, the greater influence of freezing water＇s electric conductivity on thermal conductivity is; the glaze in na- ture is greatly influenced by freezing water＇s electric conductivity.关键词
