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这四种燃料中最为理想的燃料。
Under the different liquid fuel combustion driving conditions of toluene, benzene, kerosene and ethanol, the equilibrium component of the combustion chamber of the pneumatic CO2 laser, the distribution of the small signal gain along the flow field and the output power of the laser were numerically simulated. The performance of the four fuels was analyzed. The results show that toluene is the most ideal of the four fuels.
