摘要

用Smagorinsky-Lilly亚网格尺度湍流模型和EBU亚网格尺度湍流燃烧模型，对燃料环缝进口的丙烷-空气旋流湍流燃烧进行了大涡模拟（LES），并且用二阶矩（SOM）统观湍流燃烧模型进行了RANS模拟，将模拟所得统计平均的热态三个方向速度，湍流度，温度，丙烷、氧和CO2浓度分布和详细的实验数据对比.结果表明，LES-EBU大涡模拟的统计结果不如RANS-SOM模拟结果.因此，EBU亚网格尺度湍流燃烧模型有待改进.RANS-SOM模型可以进一步在预报工程中的旋流扩散燃烧中应用.

Abstract

Simulation of propane-air swirling diffusion combustion was carried out by large-eddy simulation (LES) using the Smagorinsky-Lilly SGS turbulence model and the EBU SGS combustion model

and by RANS modeling using the second-order moment (SOM) combustion model.The simulation results were compared with detailed experimental results for three components of statistically averaged and fluctuation velocities

propane

oxygen and CO2 concentration distributions.The results indicate that the RANS-SOM results are better than the LES-EBU results.Hence the EBU SGS combustion model needs to be improved and the SOM combustion model can be further used to predict engineering swirling combustion.
