Measurement of Liquid Sheet using Laser Tagging Method by Photochromic Dye

Liquid atomization system has been extensively applied as the most significant process in many industrial fields. In the internal combustion engine, the combustion phenomenon is strongly influenced by the spray characteristics of the fuel given by the atomization process. In order to completely unde...
