Application of Digital Image Processing Method for Spray Characterization

From water sprinklers to combustion devices of launch vehicles, the applications of the liquid injectors are innumerable. Owing to the usage of non-renewable sources, there is a global movement towards improvement in the existing combustion systems. Efficiency and fuel emissions are influenced by fuel spray characteristics. One of the techniques used to capture the information on spray characteristics is highspeed shadowgraphy. Estimation of the required parameters needs analysis of image series. An automated method to replace tiring manual calculations makes it the job of a few seconds. The basic tools of image processing are employed in this study to ease the computation.
