通过RPH-80型可程序恒温恒湿试验箱研究了温度增量对圆柱体冰块融化速率的影响。研究结果表明:试验箱的温度在0℃~50℃区间内,随着温度增量的增大,圆柱体冰块的融化速率逐渐加快。通过数据分析,得出了圆柱体冰块的温度增量与融化时间、融化速率都呈多项式函数规律变化。选取温度增量为20℃的冰块融化过程进行ANSYS数值仿真验证,得出:圆柱体冰块棱边部分最先开始融化;随着时间的增长,冰块的侧面比上表面开始融化的时间早,这亦与实际的融化状况相符。
The effect of temperature increment on the melting rate of cylinder ice cubes was studied by RPH-80 programmable temperature and humidity chamber. The results show that the temperature of the chamber is in the range of 0 ℃ ~ 50 ℃, and the melting rate of the cylinder ice gradually increases with the increment of temperature. Through data analysis, the temperature increment and melting time of cylinder ice cubes are obtained, and the melting rate changes in a polynomial function. The ice melting process with temperature increment of 20 ℃ was simulated by ANSYS. The results showed that: the edge of the cylinder ice cube began to melt first; as time went on, the side of the ice cube began to melt longer than the upper surface Early, this also agrees with the actual melting status.
