本文采用直接数值模拟和详细化学的方法研究了湍流含氧合成气非预混射流火焰的标量结构。研究了雷诺数对火焰结构的影响，并分析了在相同雷诺数下，氧-燃料合成气火焰和合成气-空气火焰标量结构的差异。模拟了雷诺数为3000和6000的两种氧-合成气火焰和雷诺数为6000的一种合成气-空气火焰。这些研究表明，与合成气-空气火焰相比，氧化剂中CO2的存在对全氧燃烧合成气火焰的标量结构有着深刻的影响。
This study addresses the scalar structure of turbulent oxy-fuel syngas non-premixed jet flame in the context of direct numerical simulation (DNS) and detailed chemistry. The main objective is to identify the influence of the Reynolds number on oxy-fuel flame structure, and to clarify the differences of scalar structures between oxy-fuel syngas and syngas-air flames at a similar higher Reynolds number. Two oxy-syngas flames at Reynolds numbers of 3000 and 6000 and one syngas-air flame at Reynolds number of 6000 were simulated. These studies show that the existence of CO2in the oxidant has a profound effect on scalar structure of oxy-fuel syngas flame compared to syngas-air flame.
