To unravel the liquid-jet breakup process in the nondilute region, a newly developed system of real-time X-ray radiography, an advanced digital image processor, and a high-speed video camera were 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 wall- and free-jet tests were conducted to study the effect of wall friction on the jet breakup process.
