| 摘 要： | 在计算流体力学数值分析软件基础上，运用数值方法模拟了陶瓷蜂窝蓄热体的蓄热换热过程，得到了蓄热体及气体的轴向温度分布曲线，分析了温度随时间的变化规律，同时讨论了换向时间、烟气入口温度、蓄热体高度、蓄热材料比热等参数对热饱和时间的影响，为进一步研亮蓄热式换热机理提供了初步的理论依据．

| Abstract: | Heat transfer of the ceramic honeycomb regenerator was numerically simulated based on the computational fluid dynamics numerical analysis software. The longitude temperature distribution curves of regenerator and gas were attained. And the variation of temperature with time was analyzed. In addition, the effects of some parameters such as switching time, gas temperature at the inlet of regenerator, height of regenerator and specific heat of the regenerative materials on heat saturating time were discussed. It provided primarily theoretic basis for further study of regenerative heat transfer mechanism. |
