Abstract

For the study of a transient gas jet used in gas diesel engine, it is important to investigate the growing processes of the jet. In a certain region of injection velocity from a round nozzle, it has been confirmed that transient jets are composed of the laminar jet in the downstream and the turbulent jet in the upstream. We called the jet with characteristics of laminar sub-jet and called the jet with characteristics of turbulent main-jet. The image processing system was constructed to measure tip penetration and cross section of each jet at various times from the injection start. A jet was visualized by CCD camera using schlieren method and a jet was shown in digital by some image processing algorithms. The image processing developed in the shape-measurement will provide an effective method.
