概要	Surface phenomena of liquid jets into still air are numerically investigated. The liquid and air are treated as a single continuum with dynamically evolving interfaces captured by the level-set method. The jets considered are laminar: the jet exit Reynolds number ranges from 480 to 2300, with the Weber number of 3.1-28 000. The liquid/air density ratios are about 10(3). In comparison with an empirical correlation, the present simulations reasonably predict the breakup lengths of round liquid jets at low Weber numbers. The development of the surface wave is captured and the breakup mechanisms are discussed referring to a conventional classification chart. The breakup phenomenon at high Weber and Ohnesorge numbers is also analyzed.
