摘要
本文对管内液体冻结过程的传热进行了分析,分别利用改变变量法和等效热容法计算,对一维空间变量的问题,利用改变变量法给出了新的计算方法.将数值计算的结果与实验值及文献值进行了比较,吻合较好,本文所报道的方法,可适用于有相变潜热的非线性的热传导问题.
In this paper, the heat conduction of freezing of liquid in pipe was analyzed. The methods of transforming variable and equivalent heat capacity were used for calculation respectively. A new calculation method was used with the transforming variable method for one dimensional variable problems. The calculated values agreed well with the experimental and reported values. This method could be used for solving non-linear heat conduction problem involving latent heat.
