- 摘要:
- 为了研究一种适用于亚燃冲压发动机燃烧室的蒸发式火焰稳定器方案,采用PDF燃烧模型对其燃烧特性及供油匹配进行了流动及两相燃烧数值模拟与分析,重点研究了不同主燃区/局部供油匹配以及不同主燃区供油浓度分布等对燃烧性能的影响,获得了燃气温度峰值与均匀性相对优化的供油方案。
- Abstract:
- To study an evaporative flame-holder suitable for the ramjet combustor, the numerical simulation and analysis of two-phase combustion flow field for combustion characteristics and the fuel supply matching was carried out based on PDF combustion model. The influence of different main combustion zone / local fuel-feeding matching and fuel-feeding density distribution in different main combustion zone on the combustion performance were studied emphatically. An optimization fuel-feeding scheme for peak value and uniformity of gas temperature were obtained. The calculation result of the scheme is rational. It has an important significance for the optimization design for the fuel-feeding scheme of the evaporative flame-holder.
