摘要
Abstract
Liquid distribution in structured packing can be experimentally measured by liquid collecting,conductivity tracing,fiber-optic sensors,tomography and laser induced fluorescence technique. These experimental methods are effective,but there are also some deficiencies. The principles,implementations and deficiencies of these experimental methods are introduced and discussed. Tomography and laser induced fluorescence technique are elaborated. Both techniques realize visualization of liquid distribution and obtain liquid holdup,but there exist the problem of how to effectively remove background noise. Compared with tomography,laser induced fluorescence technique is novel,reliable,easy to implement and safe. Finally,new directions of laser induced fluorescence technique in future applications are discussed,including combination with particle image velocimetry or high-speed camera,re-extraction of experimental data and fabrication of experimental structured packing.关键词
