摘要

在保持燃烧室的扩压器尺寸、外机匣最大直径以及燃烧室出口尺寸与单环腔燃烧室一致的前提下

将燃烧室重新设计为径向分级的双环腔结构.采用相同的物理模型

用Fluent软件对单、双环腔主燃烧室分别进行全流程的三维数值模拟.结果表明

采用双环腔燃烧室

可明显提高燃烧室的总压恢复系数、燃烧效率;降低燃烧室出口温度分布系数、NOx/CO等污染的排放

尤其是慢车状态下的CO排放.用双环腔燃烧室置换单环腔燃烧室是可行的.

Abstract

The combustor was redesigned into dual annular structure in radial direction

under the precondition that the diffuser

outer case and exit dimension are kept consistent with single annular combustor(SAC).With the help of the same physical models

a 3-Dsimulation for full-flow process in both SACand dual annular combustor(DAC) was conducted in the Fluent code.By using the DAC

it shows that the total-pressure recovery coefficient and combustion efficiency can be improved remarkably

the exit temperature distribution coefficient of the combustor and NOx/COemission

especially for COemission under slowrunning state

is reduced accordingly.
