摘要
针对氢氧燃烧中间加湿过程,建立了燃烧掺混及水蒸气流中冷却水液滴蒸发的数学模型,采用欧拉-拉格朗日方法对燃烧器中氢氧加湿燃烧及冷却水喷雾蒸发过程进行了一维(1D)数值仿真,得到了燃烧器内蒸汽压力、温度等物理量分布及冷却水液滴的运动变化过程,并针对含湿量不同的氢氧入口条件及冷却水工况进行了计算,分析了各参数变化对掺混燃烧过程的影响,为氢氧加湿燃烧过程分析和燃烧室的初步设计提供参考。
A new mathematical model of humidified hydrogen-oxygen combustion is built to describe combustion blending and cooling water evaporation process. One-dimensional simulation of different hydrogen-oxygen inlet and cooling water conditions are carried out to get the inlet parameters of influencing on humidified combustion by Euler-Lagrange method. The conclusion can provide a reference for analyzing humidified hydrogen-oxygen combustion process and designing combustion chamber.
