摘　　要：针对选配文丘利型油燃烧器的燃油锅炉中液雾燃烧的特点 ,提出了一种数值模拟分析模型及处理方法 ,据此数值模拟了某单只文丘利油燃烧器出口的气液两相流动与燃烧 ,给出了流场中的速度场、温度场以及浓度场的分布信息 。According to the characteristics of spray combustion in the oil-fired boiler equipped with Venturi burner, the analytical model and processing method were developed. The numerical simulation of the gas-liquid two-phase flow and combustion in the outlet of Venturi burner was presented. The particle tracking and vaporization undergoing were described, and distributions of pressure, velocity, temperature and ingredient concentration were provided. By theoretical analysis and experimental results, it is proved that the numerical results are credible. The numerical results can be used to improve the design and operation of this boiler.
