摘要
将高强度燃烧室中普遍存在的燃烧振荡问题通过一维简化数学模型进行分析.在建立控制方程组的基础上给出了一维脉动波传播的方程解形式,并对燃烧区域内放热特性进行讨论.通过所建立的数学模型对燃烧振荡特性进行理论分析,为燃烧装置的设计及其稳定运行提供参考依据.利用燃烧振荡现象来强化燃烧,并且降低燃烧振荡对燃烧装置的危害.
Based on some reasonable hypotheses, complex three-dimensional nonlinear problem of combustion oscillation, which often occurs in high-intensity combustion chambers, was simplified to one-dimensional mathematical model. Analytical solutions of one-dimensional oscillation waves were given herein, and exothermic characteristics of combustion fields were discussed as well. The mathematical model built here affords theoretical guidance for explaining the characteristics of combustion oscillation phenomena, supplies references for effective designs and smooth operations of combustion equipments, and aims to reduce the occurrence of combustion oscillation problem finally.
