The numerical simulation on cooling effect of microcapsulated phase change material suspension in laminar thermal developing section

摘要：

The microcapsulated phase change material (MEPCM) suspension has obtained more and more attentions. At present, the numerical models concerning MECPM suspension are generally reduced to single-phase models. In this paper, a novel two-phase model is constructed. By use of this numerical model, the cooling effect of MEPCM suspension under different velocities, heat uxes and concentrations is calculated. The results are at variance with experimental results qualitatively. It is discovered that the cooling effect of high concentration MEPCM suspension at low heat ux is best, but will go down quickly as the heat ux increasing further. The cooling effect of flow concentration is better than that of water in the entire range of heat flux.
