摘要
对相变材料在水平管内的接触熔化传热过程进行了一般性的研究,给出有关问题的统一表达式。以水平圆管、椭圆管为例对所得公式进行具体计算与推导,所得结果得到了有关文献的佐证。
The heat transfer of contact melting of phase change material (PCM) inside horizontal tube was generally analyzed. The unified mathematic expressions of the characteristic parameters for the contact melting proeesses are obtained. Applying the expressions to the eontaet melting inside the horizontal eylinder and elliptieal tube, the praetieal methods and steps were given. Compared with the results in the published lectures, it is shown that the analysis is valid.
