摘　　要：采用自编计算程序,在任意曲线坐标系下对带扩压器、涡流杯、火焰筒、内外环冷却通道与弯管的回流环形燃烧室三维两相化学反应整体流场进行计算.数值预测火焰筒头部结构参数对燃烧流场的影响.所得计算结果与实验数据符合较好,结果表明:采用的数学模型和计算方法合理,该软件可供回流燃烧室优化设计与研制使用.In the arbitrary curvlhnear coordinates, a computer cocte was aevelopea tor simulating the integrated three-dimensional two-phase reacting flow field in a reverse-flow annular combustor which consists of the diffuser, swirler cup, flame tube, inner annulu ses, outer annuluses and bend. The influence of different primary hole parameters on reac- ting flow fields was studied numerically. Both experimental data and numerical results were in reasonable agreement, and it reveals that these mathematical models and numerical meth- ods are reliable and may be applied to the optimization design and development of the re- versed-flow annular combustor.
