中文摘要：

基于质量、动量、能量守恒原理,建立了碳粒燃烧的数学模型,对相互影响的两颗碳粒的定常燃烧过程进行了数值模拟.通过改变碳粒间的距离、气流速度、来流方向等参数,计算得到了两碳粒周围在各种工况下的速度、组分及温度的分布,并详细分析了各参数的改变对两碳粒燃烧过程的影响,揭示了碳粒与碳粒、碳粒与气流之间相互作用的规律.结果表明：适当增加碳粒间距和来流速度有利于燃烧的进行;碳粒表面温度随来流方向的改变有规律地变化.

英文摘要：

The mathematical model of combustion of carbon particles, which based on mass, momentum and energy conservation law, was established. Effects of different combustion parameters, including particle distance, air velocity and incoming flow angle, were numerically studied for steady two interactive car- bon particles combustion process. Detailed information of distribution of the velocity vector, the temperature and the components＇ mass fraction around the carbon particles were obtained. The effects of all these condition on the carbon combustion were analyzed. The mutual influence rule between the particle-particle and the particle-flow were also obtained. The results show that increasing particle spacing and flow velocity appropriately is conducive to combustion. Besides, the surface temperature of carbon particles changes regularly with the alternation of flow direction.
