| Abstract: | In the arbitrary curvilinear coordinates,a computer code was developed for 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 annuluses,outer annuluses and bend.The influence of different primary hole parameters on reacting flow fields was studied numerically.Both experimental data and numerical results were in reasonable agreement,and it reveals that these mathematical models and numerical methods are reliable and may be applied to the optimization design and development of the reversed-flow annular combustor. |
| Keywords: | numerical simulation reverse-flow annular combustor two-phase reacting flow field primary hole swirler cup |
