High-speed 3D reconstruction of liquid surfaces in sprays

Popis výsledku v původním jazyce

Accurately visualizing liquid breakups in sprays is important for a wide range of spray appli- cations as well as for understanding the process of liquid atomization. However, spray data are usually generated either from 2D imaging techniques or using point measurement approaches (using for example Phase Doppler Anemometry - PDA). Relatively few measurements have been performed in 3D which is necessary to obtain the complete characterization of a spray system and to understand how it is formed. In addition, the 3D imaging techniques that are currently available are usually based on time-averaged data and do not have the capability of 3D temporally-resolving fast liquid breakup phenomena. We have developed a novel technique called Fringe Projection - Laser Induced Fluorescence, FP-LIF, with the possibility of gener- ating snapshot 3D surface reconstructions of irregular liquid structures, such as liquid sheets, ligaments, blobs and other large liquid bodies. The advantage of this technique is that only
