摘要：通过均相流体模型、湍流k ε模型和EBU(EddyBreak Up) Arrhenius燃烧模型 ,选用Simple格式对管中戊烷和空气的燃烧实例进行了数值求解。其结果反映了燃烧导致的爆炸过程中管内流场各参数的变化规律 ,揭示了管内燃烧、流动、湍流之间的正反馈耦合关系 。
To explore the propagation of turbulent flame in a large horizontal tube, numerical simulation was carried out by using homogeneous fluid model, standard κ-Ε turbulent model, EBU-Arrhenius combustion model and two-dimensional homogeneous reaction model, and Simple scheme was adapted to solve the models. Example computation was performed for the pentane-air suspension flow, and variations of different parameters in the tube during the process of propagation of turbulent flame induced by combustion were obtained. The positive feedback mechanism among combustion, propagation and turbulence was revealed, which agrees well with both experimental results and other numerical results.
