实测冰-水侧向界面热力学融化速率
Analysis of measured thermodynamic melting rate of lateral interface between ice and water
摘要
Abstract
The open waters were dug to simulate ice‐channel system in Ulansuhai Lake during melt period and the change of lat‐eral interface between ice and water was continuously observed .On the basis of the measured data ,analysis was conducted to study the change of lateral interface and the influencing factors on thermodynamic melting rate .The results showed that the shape in the middle of the interface was like a straight line and the bottom interface presented an arc shape .However ,the top in‐clined inside or outside under the influence of air temperature .Air temperature ,as a principal factor ,influenced the melting rate , and the melting rate increased with increasing air temperature .Because higher wind speed did not only usually accompany with lower air temperature but also accelerated the evaporation to reduce the water temperature ,melting rate decreased with increas‐ing wind speed .The wind pulled the water body to produce eddy at windward side ,accelerated heat exchange and reduced water temperature ,and finally reduced the melting rate .Moreover ,the correlation between melting rate ,air temperature as well as wind speed was established with binary regression .关键词
