For the study of the combustion in a transient gas jet used in gas diesel engines, it is very important to investigate the entrainment process of the surroundings of the jet. In this study, a path line method utilizing a CCD random shutter camera with various shutter times was applied. Large (40 μm), lightweight microballoon particles are used for scattering the path lines of the surroundings and fine particles (0.75 μm) are used for visualizing the approximate shape of the jet. The transient gas velocity was also measured with a two-component laser Doppler velocimeter (LDV). Consequently, (1) the jet configuration and the entrainment process could be visualized simultaneously, and (2) this path line method was found to be very useful for estimating the air mass entrained because of the good agreement with the values obtained using LDV.
