| 摘 要： | 对斯特林发动机燃烧室氧-柴油无焰燃烧进行数值模拟。研究表明：氧-柴油无焰燃烧相比于传统氧-燃料燃烧需要卷吸更多的烟气来对纯氧进行稀释。直流燃烧室和旋流燃烧室内实现无焰燃烧的引射比分别为32和11.5，旋流燃烧室有助于无焰燃烧的实现。氧-柴油无焰燃烧的火焰峰值温度比传统燃烧模式低600 K左右，火焰峰值温度大幅下降。氧-燃料模式下燃烧室温度变化在20%以上，而氧-柴油无焰燃烧模式下温度变化小于15%，燃烧室温度均匀性显著提高。

Numerical study on flameless oxy-diesel combustion in stirling engine combustor |

| Abstract: | The Stirling engine combustor with Flameless Oxy-diesel combustion was numerically simulated. Theres-ults show that Flameless oxy-diesel combustion compared to conventional Oxy-fuel combustion needs more flue gas todi-lute the pure oxygen. Swirl combustor helps achieve flameless combustionthe ejection ratio of direct flow combustor and swirl combustor is 32 and 11.5, respectively. The peak temperature of Flameless oxy-fuel is decreased significantly,approx-imately 600 K lower than the the peak temperature of traditional combustion mode. The temperature uniformity of Stirling engine combustor was significantly increased by achieving Flameless combustion, the normalized spatial temperaturevari-ation is more than 20% for Oxy-fuel combustion and less than 15% for Flameless oxy-diesel combustion. |
