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。
A mathematical model of diffusion combustion in an axisymmetric sudden expansion combustor was established. The SIMPLER method was used to numerically solve a variety of operating conditions. The calculated results accorded with the basic theory of diffusion combustion and physical reality, and could basically replace the physical model experiment. Design calculation provides a new means.
