为解决含硼富燃燃气二次燃烧数值模拟时燃烧模型选择问题，提高数值模拟精度，根据二次燃烧实验装置建立简化物理模型，以King模型为硼粒子点火燃烧模型，以有限速率/涡耗散模型为气相燃烧模型，结合Fluent软件UDF功能，自编硼粒子点火燃烧程序，对实验工况进行数值模拟，得到流场参数和流场结构分布。模拟结果与实验结果对比分析表明，采用King模型的计算结果，可较好地预测硼粒子点火距离、流场压力等参数。

In order to choose models and improve the precision of numerical simulation in the combustion chamber for fuel-rich gas containing boron particles,a simplified entity model was built. An experiment mode was simulated using Finite-Rate/Eddy-Dissi-pation model in gas combustion and UDF of King model in particles combustion.Comparing with the results of the experiment, it in-dicates that the simulation with King Model can calculate the length of boron ignition and the pressure accurately.
