新概念燃烧室应用高温空气燃烧技术的数值模拟

为了将高温空气燃烧技术(HiTAC)应用于航空发动机燃烧室设计,本文设计了一个全新概念的燃烧室.该燃烧室将小型预燃室燃烧产生的高温贫氧烟气直接喷入与其连接的火焰简内组织成高温贫氧空气燃烧.本文对该燃烧室内的燃烧状态进行了数值分析.结果表明:该新概念燃烧室具有温度均匀分布,壁面有效冷却,NOx低排放,节约燃油等优势.

The numerical simulation of HiTAC technology apply in new conceptual combustor

In order to apply the HiTAC technology in air-turbine combustor design,this paper present a new conceptual combustor.The conceptual basis of the high temperature and low oxygen air are created by mini-precombustor inject directly to flame tube which is linked to mini-precombustor.By analyzing the combustional status of the new conceptual combustor,the results showed that the excellent advantages have obtained by the new conceptual combustor such as the temperature distribution uniform,the wall cool effectiv...
