摘要:
采用PREMIX模块模拟乙烯-氧化亚氮(C2H4-N2O)预混体系在0.1～1.5 MPa下层流火焰传播速度,得到不同压力和氧/燃比下乙烯-氧化亚氮体系的火焰传播速度、火焰温度和燃烧质量流率变化。同时,采用层流火焰传播测试仪器对乙烯-氧化亚氮预混体系的层流火焰传播速度进行实际测定,通过对比火焰传播速度的测量值与计算值,验证选用模型的准确性和计算方法的可靠性。试验结果表明:所选用的USC机理模型可适应于研究预混气体层流火焰燃烧计算,当量比等于1.18,压力0.1 MPa时层流火焰传播速度达到最大值; 当量比等于1.18,压力1.5 MPa时层流质量燃烧流量达到最大值; 当量比为1.35,压力1.5 MPa时层流火焰达温度到最大值。
Abstract:
The laminar flame propagating velocity of C2H4-N2O(ethylene nitrous oxide)premixed mixture was simulated by PREMIX module at the pressure of 0.1～1.5 MPa. The variation of flame propagation velocity, flame temperature and mass flow rate of C2H4-N2O mixture under different pressure and oxygen/fuel ratio was obtained. A laminar flame propagation test instrument was used to measure the laminar flame propagating velocity of C2H4-N2O premixed mixture. The measured and calculated value of the flame propagating velocity are compared to verify the accuracy of the chosen model and reliability of the calculating method. The results show that the model with USC mechanism can be adapted to calculate the laminar flame combustion characteristics of the premixed gas. The flame propagating velocity reaches its maximum value as the equivalence ratio is 1.18 and pressure is 0.1 MPa. The laminar burning mass flow rate reaches its peak as the equivalence ratio is 1.18 and pressure is 1.5 MPa. The laminar flame temperature reaches its peak as the equivalence ratio is 1.35 and pressure is 1.5 MPa.
