| 摘 要： | 对于多孔介质内往复流动下超绝热燃烧（简称RSCP）系统，如果多孔介质的孔隙分布均匀、物性参数保持不变、化学反应为不可逆反应而且反应完全，那么，稳定燃烧过程中，多孔介质内最大温度和温度分布几乎不受往复半周期长短的影响。依据这一特点，用过滤燃烧模型，讨论了往复半周期无限长和无限短两种极端情况下最大温度值和温度分布，得出两种极端情况适用于通常工况的简单模型理论解。

| Abstract: | For superadiabatic combustion in porous media with reciprocating flow (RSCP), in the cases of homogeneous porous medium, constant physical properties, irreversible and complete combustion reaction, during the combustion process, the maximum and the shape of temperature distribution inside the porous media are not dependent on the cycle period. In this paper, based on the temperature distribution characteristics of RSCP, the maximum and the shape of temperature distribution inside the porous media with infinite long and infinite short (zero) half cycles are analyzed. An approximated solution to the temperature distribution in RSCP at finite half cycles is obtained by properly combining the theoretical solutions in the filtration combustion for two extreme cases. |
