摘要
建立了轴对称突扩燃烧室内扩散燃烧过程的数学模型,采用SIMPLER方法对多种工况进行了数值求解,计算结果符合扩散燃烧基本理论和物理真实,基本可以代替物理模型实验,为燃烧室的设计计算提供了新的手段。
Develops a mathematical model for the diffusive combustion process in an axisymmetrically suddenly-expanding combustor. Various operation modes are thus solved numerically by way of the SIMPLER method,and the results show that they are in accordance with both the basic theory of the diffusive combustion and the physical reality. The computation, Therefore, is considered as a newly-developed method instead of physical modelling in combustor design.
