燃烧驱动气动CO2激光器几种液体燃料性能差异的数值模拟
-
摘要: 在甲苯、苯、煤油和乙醇四种不同液体燃料燃烧驱动条件下，对气动CO2激光器燃烧室的平衡组分、小信号增益沿流场方向的分布及激光器的输出功率进行了数值模拟，计算对比分析了该四种燃料的性能。计算结果表明甲苯是气动CO2激光器四种燃料中最为理想的燃料。Abstract: The combustion-chamber’s composition、small-signal gain distribution along flow direction and laser’s power and specific power of the combustion-driven gas-dynamic CO2 laser with toluene、benzene、kerosene and alcohol separately combustion driven were numerically simulated. The four different conditions were compared and the results will be referential to CO2 laser’s study. The results indicated toluene is an optimum fuel of the four gas-dynamic CO2 laser’s fuels.
