Local measurement of oxygen transfer around a single bubble by planar laser-induced fluorescence
چکیده انگلیسی

The aim of this work is to develop a non-intrusive experimental technique to measure oxygen concentration in a liquid phase. This technique relies on the planar laser-induced fluorescence (PLIF). In its classical version, PLIF consists in viewing the presence of a fluorescent dye in a liquid phase by means of a laser sheet. Digital image analysis gives the relationship between local grey levels and the dye concentration. The principle of the oxygen concentration measurement rests on the fact that the oxygen molecules inhibit this fluorescence, in proportion to their concentration. After calibration, analysis of the grey levels gives an image of the 2D field of oxygen concentration.
