摘要:
通过将融化的石蜡注入泡沫铝构成复合相变材料,能有效改善复合相变材料石蜡的导热性能.以两边定壁温、两边绝热的正方形泡沫铝复合石蜡相变材料为研究对象,利用双温度模型分析了纯石蜡、低密度泡沫铝复合石蜡、高密度泡沫铝复合石蜡的传热特性.采用相似理论得出双温度模型的理论解形式,并以显热容法数值模拟了相变传热过程.结果表明:经过简化的双温度模型的理论解与数值解高度吻合,在正方形中二维传热可以简化为一维传热来进行求解;泡沫铝复合石蜡相变材料的导热系数比纯石蜡有了较大改善;相变过程中石蜡和泡沫铝之间的温度差不可忽略.
Abstract:
By pouring the melting paraffin into foamed aluminum, the composite phase change material phase change material(PCM)was constructed and the thermal conductivity of PCM was greatly improved. The square shape composite PCM with constant temperature on two sides and adiabatic boundary on another two sides was selected as a research object. Heat-transfer characteristics of pure paraffin, low density foamed aluminum PCM, high density foamed aluminum PCM were analyzed using the two-temperature model. The form of the analytical solution of the two-temperature model was deduced by the similarity theory. The numerical modeling of the heat-transfer process was made by using the apparent heat capacity method. The results show that the theoretical resolution form of the simplified two-temperature model is highly consistent with the numerical solution. Also, two-dimensional heat transfer can be simplified as one-dimensional heat transfer in the square shape. In addition, the heat conductivity coefficient of foamed aluminum PCM is highly improved compared with the pure paraffin. The temperature difference between the paraffin and the foamed aluminum in the phase change process cannot be ignored.
