Preliminary investigation of gas-liguid separation in twisted flow aerosol singlet oxygen generator

  • 摘要: 为解决气液分离问题,提出了粒径可控离心分离的设想,即通过某种雾化技术产生粒径可控的液滴,然后根据液滴的粒径确定气液分离所需要的离心力,在高速旋转的叶片所产生的离心力作用下液滴一边与气流发生反应一边完成气液分离。为验证这一思想,搭建了一台旋流喷雾式单重态氧发生器(TFA-SOG),并通过计算流体力学模拟和实验对这台TFA-SOG进行了研究。研究结果表明,模拟的气液分离效率与实验的相一致,粒径可控离心分离的设想是可行的。
