| 摘 要： | 对一种应用于工业炉的蓄热器、太阳能中央接受塔的储能系统微米级颗粒度下含有无机盐的陶瓷多孔材料的熔化加热过程进行理论研究,在研究中考虑陶瓷基体和无机盐热物性、空隙率和融盐汽化率的影响。计算结果表明,较大的陶瓷骨架孔隙率和相变潜热、较小的导热系数造成温度和固液界面位置的变化变慢,但对气相界面的生成和移动影响不大。

| Abstract: | The theoretical analysis of heat transfer in the melting process in the porous media saturated with salt which is used in the regenerator in industrial stove and central receiver of solar energy system is present. The effect of thermal properties of the salt and ceramic, porosity of the ceramic and the gas phase in the melt salt is considered. The calculated results show that higher ceramic porosity and latent heat and lower heat conductivity make the movement of interface between solid and liquid slower but have fewer effects in the creation of gas and the movement of interface between gas and liquid. |
