| 摘 要： | 盘管式蓄冰传热瓶颈出现在冰层处,考虑在管外加入一些金属丝来促进管外换热从而提高蓄冰效率.为了描述管外扩展表面给结冰过程带来的影响,把管外金属丝和水的混合区域考虑为多孔介质区域,建立了合理的数学物理模型,进行了理论计算,并采用了密度随温度接近抛物线变化来研究水的自然对流对结冰过程的影响.通过计算,发现自然对流对温度分布的...

| Abstract: | Shortcomings of the ice-on-coil thermal storage heat appear in the ice.Adding some metal wire around the tube may improve freezing efficiency.In order to describe the result of freezing process on extended surface,regarding wire and water mixing region as porous media,reasonable mathematical physical model is established and theoretical calculation is conducted.Density variation with temperature is used to study influ-ence of the water natural convection on the freezing process.Calculation finds that effect... |
