| Abstract | Liquid jet breakup mechanisms and processes have been studied extensively over the last 50 years. However, since the region near the jet injector is too dense and optically opaque, conventional visualization cannot be applied with satisfactory experimental results. To unravel the liquid jet breakup process in the nondilute region, a newly developed system of real-time x-ray radiography together with an advanced digital image processor and a high-speed video camera was used in this study. Based upon recorded x-ray images, the inner structure of a liquid jet during breakup was observed. The jet divergent angle, jet breakup length, and void fraction distributions along the axial and transverse directions of liquid jets were determined in the near-injector region. Both walland free-jet tests were conducted to study the effect of wall friction on the jet breakup process. |
