摘要:
 采用高速纹影系统和定容燃烧弹对氢气预混层流燃烧球形膨胀火焰的燃烧速度特性进行研究.分别在改变
燃空当量比(0.3~6.0)、初始温度(300~450,K)、初始压力(0.1~0.3,MPa)的条件下,对比分析Markstein 长度、火
焰传播速度、火焰燃烧速度的变化规律,得出了燃烧速度随燃空当量比、温度、压力变化的拟合公式,并应用
CHEMKIN-PRO 进行了相应的不同化学反应机理的模拟计算与敏感性分析.研究结果表明,氢气的火焰燃烧速度与
传播速度随燃空当量比、温度、压力的变化规律相似,随着燃空当量比的增加其值先增加后减少;随着温度的增加
其值增加,且增加的相对幅度较大;中等浓度时,随着压力的增加其值增加,而低浓度和高浓度时随压力的增加而
减小.拟合得到的燃烧速度与当量比呈4 次多项式关系,温度指数因子与当量比呈3 次多项式关系,压力指数因子
与当量比呈分段线性关系
Abstract:
 Using high-speed schlieren photography,the Markstein length,flame velocity, burning velocity of
hydrogen-air outwardly propagating spherical laminar premixed flame are studied in a constant volume combustion
bomb at different fuel equivalence ratio(0.3—6.0),temperature(300—450,K)and pressure(0.1—0.3,MPa). The
formula of burning velocity with fuel equivalence ratio,temperature and pressure is also fitted. Moreover,
calculations are performed by using CHEMKIN-PRO with different mechanisms. The results show that flame velocity
and burning velocity vary similarly with fuel equivalence ratio,temperature and pressure. With the increase of fuel
equivalence ratio,flame velocity and burning velocity increase first and then decrease. As temperature rises,
velocity rises too. As pressure increases,velocity increases at moderate concentration,but decreases at high and low
concentration. The correlation between burning velocity and fuel-equivalence ratio is quartic polynomial,the correlation
between temperature exponent and fuel equivalence ratio is cubic polynomial,and the correlation between pressure
exponent and fuel equivalence ratio is piecewise linear.
