摘要
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 0.07m/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 ve-locity 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.
