| 摘 要： | 通过CFD方法建立了一个耦合化学反应的多孔介质二维拟均相反应器模型，研究了耗氧型惰化系统在不同工况下反应器的操作范围及工作性能。以RP-3燃油为研究对象，采用Fluent 17.0软件的多孔介质单温度模型，通过UDS （User Defined Scalar）添加固相能量方程，采用源项形式添加化学反应热到固相能量方程。研究了不同参数对反应器起燃过程的影响，并给出了起燃过程内反应器催化床温度的变化过程。结果显示：反应器起燃过程中，催化床温度十分不均匀；RP-3摩尔分数的增加可大幅度缩短起燃时间，并且可降低起燃温度；存在一个适宜的气体速度使得反应器能够快速起燃。

| Abstract: | A two-dimensional quasi-homogeneous reactor model of porous media coupled with chemical reactions via the CFD method is established. The operating range and performance of the reactor under different operating conditions are studied using this model. Taking RP-3 fuel as the research object, using a single temperature model of porous media in Fluent 17.0 software, we add the solid phase energy equation through UDS (User Defined Scalar), and add the chemical reaction heat to the solid phase energy equation through the source term. The effect of key parameters on the ignition process of the reactor and the temperature change of the reactor catalytic bed during the ignition process are simulated. The results show that the temperature of the catalytic bed is uneven during the ignition process of the reactor; the increase of the mole fraction of RP-3 can considerably reduce both the ignition time and the ignition temperature; an appropriate gas velocity exists to enable fast reactor light-off. |
