摘要

层流火焰速度、温度和压力测量在高温、球形膨胀乙烷-空气火焰中进行。实验是在激波管中进行的,它允许进入以前未被探索的乙烷-空气预混火焰的高温状态。化学计量乙烷-空气混合物最初被冲击加热到461-537 K, 1 atm的未燃烧气体条件。利用Nd:YAG激光火花点燃加热后的混合气体,引发层流火焰传播。采用高速OH*端壁成像及时记录球形膨胀火焰的传播,并对图像进行分析,确定未燃烧、未拉伸的层流火焰速度。测量结果与现有文献结果和动力学模型模拟(AramcoMech 3.0、NUIGMech1.3和FFCM-2)非常吻合。对现有乙烷-空气火焰速度数据进行了全面调查,以实现高保真的幂律拟合,以描述乙烷-空气火焰速度的温度依赖性。此外,还使用单线激光吸收诊断来测量燃烧气体的温度和压力。温度和压力的测量证实了激波管层流火焰法产生的火焰是绝热的和恒压的。

Laminar flame speed measurements and laser absorption characterization of high-temperature, premixed ethane–air flames
Laminar flame speed, temperature, and pressure measurements were conducted in high-temperature, spherically expanding ethane–air flames. The experiments were conducted in a shock tube, which allows access to a high-temperature regime previously under-explored for premixed ethane–air flames. The stoichiometric ethane–air mixtures were initially shock-heated to unburned gas conditions of 461–537 K, 1 atm. An Nd:YAG laser was used to spark-ignite the heated gas mixtures and initiate laminar flame propagation. High-speed, OH* endwall imaging was used to record the propagation of the spherically expanding flames in time, and the images were analyzed to determine the unburned, unstretched laminar flame speed. The measurements show close agreement with available literature results and kinetic model simulations (AramcoMech 3.0, NUIGMech1.3, and FFCM-2). A comprehensive survey of available ethane–air flame speed data was conducted to enable a high-fidelity power-law fit to describe the temperature dependence of ethane–air flame speeds. A single line-of-sight laser absorption diagnostic was additionally used to measure burned-gas temperature and pressure. The temperature and pressure measurements confirmed that flames generated using the shock-tube laminar flame method are adiabatic and constant-pressure.
