蜂窝状陶瓷蓄热体热交换过程的数值模拟

The numerical simulation of the heat transfer of the ceramics honeycomb in regenerator

将蜂窝陶瓷蓄热器的热交换方程转化为无量纲量的微分方程,并进行了数值计算。结果表明,对于蜂窝陶瓷蓄热器,其热交换温度效率和热效率,主要受二个无量纲即两个物理量群(无量纲时间、无量纲程度)的约束。通过对这两个物理量群的分析可以得出影响蜂窝陶瓷蓄热器传热效果的各种物理因素。

The differential equation of the heat transfer of the ceramics honeycomb in the regenerator is translated into nondimensional equation and calculated. The result shows that the heat efficiency and temperature efficiency is impacted by the two nondimensional parameters separately. The influencing factors to the heat transfer of ceramic honeycomb can be found by analysing the relations between the two nondimemsional parameters with the results of calculation.
