Abstract

The ignition process of an annular combustor with multiple injectors was investigated by experiments and simulations. In the numerical simulation, the unsteady Reynolds average Navier-Stokes (RANS) method, adaptive mesh refinement (AMR) and University of California, San Diego (UCSD) detailed chemistry were applied. The simulation predicted light-round process, flame merging and heat release rate were compared with the experimental results. The numerical results showed an overall agreement of the light-round process with the experimental results recorded by high speed camera. The simulated flame surface area and integrated heat release rate were in agreement with the profile of integrated light intensity of experiment. The arc-like flame, azimuthal propagation pattern of light-round and asymmetry of the flame merging were observed both in simulations and experiments. The simulation method is reliable for predicting the flame propagation in the annular combustor. Compared to experiments, the numerical method is capable of revealing more details of flow field and flame propagation, but the numerical results depends on the validation of experiments.

Key words： annular combustor light-round ignition ignition test unsteady Reynolds average Navier-Stokes adaptive mesh detailed chemistry

环形燃烧室点火过程的实验与数值研究

对多喷嘴旋流环形燃烧室的周向点火过程进行实验研究和数值模拟. 数值方法采用非稳态雷诺平均(RANS)、自适应网格加密(AMR)方法和加州大学圣迭戈分校（UCSD）详细反应机理. 将数值模拟所得的火焰周向联焰、合焰和放热率与实验结果进行对比. 结果表明，数值计算所得的火焰周向传播过程与实验中高速相机记录的火焰传播过程整体相符. 计算所得的火焰面积和放热率变化与实验所得的积分亮度变化曲线较符合. 实验和数值结果均表明，在点火过程中存在拱形火焰、周向传播模式以及不对称的火焰汇合. 所采用的数值方法能够基本模拟环形燃烧室中的火焰传播过程. 与实验相比，数值计算能揭示更多流场和火焰传播的细节，但是数值结果依赖于实验的标定.
