摘要(Abstract):

建立水流外掠冰柱实验台,分别开展了水流速度(0.02、0.03、0.04、0.05、0.06和0.07m/s)、水流温度(7、10、13、16和19℃)、冰柱直径(60、70、80和105mm)及冰柱初始温度(-12、-8和-5℃)对于冰柱融化速率的影响研究。通过对融化时间的统计和分析,获得以下结论:水流温度对于融化时间的影响呈幂函数规律;水流速度和冰柱直径对于融化时间的影响呈线性规律;冰柱初始温度对于融化时间影响较小。
The experiment table of water flow across ice pillar was established in this research which mainly analysis how the water velocity( 0. 02 m /s,0. 03 m /s,0. 04 m /s,0. 05 m /s,0. 06 m /s and 0. 07 m /s),diameter of the ice pillar( 60mm、70mm、80mm 和 105mm),the temperature of water flow( 7℃ 、10℃ 、13℃ 、16℃ 和 19℃) and initial temperature of the ice pillar(-12℃、-8℃和-5℃) influenced on the ice pillar melting rate. By analyzing the statistic of melting times,some conclusion could be got as follows: The effects of water temperature on melting time are representing as power function. The effect of water velocity and diameter of the ice pillar on melting time are representing as linear. And the influence of initial temperature of ice pillar on melting time has a minimal effect.
