摘要
利用QUICK格式对一维水力热力数学模型中的对流项进行离散,通过模拟结冰点的位置和比较不同温度、水深、风力条件下对结冰点位置的影响,主要改进了冰盖厚度发展模型,利用该模型对冰盖厚度的发展进行了模拟,通过与经验公式及实测结果进行比较,表明改进后的冰盖厚度发展模型是可靠的,可以用于金积引水渠的冰盖厚度模拟。
QUICK scheme is used to discretize the convective term in a one dimensional hydraulic and thermodynamic model. The ice positions were calculated in different weather conditions to compare the effects of air temperature, depth of water and wind speed on ice position. An ice coyer progression model was improved to simulate the ice cover process under an experiment condition. By comparing the measured result with an experimental formula, it is concluded that the improved ice cover progression model is reliable and can be used to simulate the ice cover thickness in Jinji diversion open channel.
