A numerical simulation was carried out to investigate the process of gas‐liquid reaction in a jet‐type singlet oxygen generator by using volume‐of‐fluid coupled with large eddy simulation. The coupled hydrodynamic and reaction simulations provide detailed information about the reacting flow. Results reveal that the reaction aggravates the jet instability and affects the jet structure significantly due to the differential pressure around the liquid jet. The effects of gas velocity on chlorine conversion and the yield of singlet oxygen were investigated. The key is the increasing of the interface area rather than the convection. This numerical simulation study is convenient for the design of singlet oxygen reactors and the research of gas‐liquid two‐phase flow with reaction.

射流型单重态氧气发生器中气液反应流的数值研究

利用流体体积和大涡模拟，对射流型单重态氧气发生器中的气液反应过程进行了数值模拟。耦合的流体动力学和反应模拟提供了有关反应流的详细信息。结果表明，由于液体射流周围的压差，反应加剧了射流的不稳定性，并显着影响了射流的结构。研究了气体流速对氯气转化率和单线态氧产率的影响。关键是增加界面面积而不是对流。该数值模拟研究为单线态氧反应器的设计和带有反应的气液两相流的研究提供了方便。
