摘要
为研究横向均匀液滴发生器的机理,对Cl2/He气体横向流过BHP液滴场的物理化学行为建立一维化学反应流动模型.其中气流场按不可压缩假设近似为一维均匀流动;发生于液滴内的化学反应由四种物质的反应扩散方程描述;气相中各种物质浓度由对流扩散方程描述.液滴是这些物质的源或汇,两个模型方程通过此源项相联系.对模型方程作数值求解.结果显示,氯气利用率、单态氧产率及效率与文献所提供的实验结果较为接近,反映了所建模型具备模拟混合气体与BHP液滴反应的基本能力.
To investigate mechanism in TUDOG（Transeverse Uniform Droplet Oxygen Generator）, a one-dimensional chemical reactive flow model is established to describe physical and chemical performance as mixed Cl2/He gases passing through BHP（ KOH, H2O2, H2 O）droplet field transeversely. Gas-phase flowfield is approximately considered as 1-D homogeneous flow according to incompressibility hypothesis. Chemical reaction in liquid droplet is described by reactive-diffusion equations with 4 gasous components. Concentration of gasous components are described with convective-diffusive equations. Droplets are gasous source or sink. It is shown that chlorine utility, singlet oxygen yield and generator efficiency are close to experiment results. The model is verified in simulating interactions between mixing gases and BHP droplets.
