Application of Planar Laser-Induced Fluorescence for Interfacial Transfer Phenomena

The present review describes the current achievements in applications of a planar laser-induced fluorescence (PLIF) method for diagnostics liquid films, bubbles, individual droplets, and sprays. Such flows are related with strongly curved interphases, which often results additional high errors during PLIF data quantification because laser light reflection, refraction, absorption. demonstrates that two-color approach modification regularly structured illumination resolves reflection- refraction-caused errors. latter ensures proper phase separation measurement cross-section visualization interface dynamics. former provides accurate evaluation local temperature concentration both gaseous phases even case strong variations sheet intensity. With intensified cameras, is used multi-parameter two-phase combustion sprays chambers optical access. It visualizes quantifies fuel evaporation mixing, to measure gas reveal regions pollutant formation. technique can also be easily combined particle image (or tracking) velocimetry method, evaluate heat mass transfer.
