Abstract:
In order to study the influence of the flame- holder layout on the outlet temperature distribution, combustion efficiency and total pressure loss, the numerical simulation of combustion flow field for a ramjet combustor was completed. The PDF combustion model is used to deal with the turbulent combustion. Results of numerical simulation show that the axial relative distance of flame-holder has obvious effect on combustor performance. The equivalent wide design has the best performance. The results of computation are qualitatively reasonable. It was aimed at predicting the performance characteristics of ramjet combustor through numerical simulation, and giving guidance to modification design of combustor or combustion experiments.
